Programmering plejede at handle om at lære at lave et program, men nu er det i alt. Datavidenskab^(Data) , maskinlæring, webudvikling, drift, systemadministration...you name it.

Vi tager et kig på de bedste computerprogrammeringskurser og -kurser, du kan finde gratis online. Disse computerprogrammeringskurser er ikke i nogen særlig rækkefølge. De er alle fantastiske.

Det er ikke vores opgave at beslutte, hvilken der er bedst. Du skal beslutte, hvad der er bedst for dine karriere- eller hobbymål. Alle har mindst et af de bedste programmeringssprog at lære i dag^{(best programming languages to learn today)} . Vi starter med dem, du med mindre sandsynlighed har hørt om, og tilføjer de mere populære til sidst.

Kaggle

Hvis du er på vej i retning af datavidenskab, har Kaggle en række mikrokurser, som du vil nyde, alt sammen, der fører til at gøre dig til dataforsker. Der er en serie på 14 klasser, hver omkring 5 til 10 lektioner lang. Den bedste del, udover at være gratis, er, at du ikke behøver at installere nogen software. 

Al din programmering og test udføres lige inde i en Kaggle Notebook . Hvilken bedre måde at lære Python , SQL , Machine Learning og andre datavidenskabelige færdigheder?

Pros	Cons	Languages/Technology
In-browser coding exercises	Only 15 courses	Python

Stanford University

Det er ikke gratis at gå på Stanford University , men deres Stanford Engineering Everywhere ( SEE ) kurser er det. Udgivet under en Creative Commons -licens, SEE - materialet er gratis og åbent for genbrug. Tjek CC-licensen for detaljer. 

Computerprogrammeringskurser^(Computer) udføres på universitetsstil og er ret dybdegående. Hvis du overvejer at tage en grad i datalogi^{(Computer Science)} , men ikke er sikker på, om det er noget for dig, vil disse kurser løse det.

Dash ved generalforsamlingen^{(Dash by General Assembly)(Dash by General Assembly)}

General Assembly er en online læringstjeneste med for det meste betalte kurser. Men ét kursus er overvejende fremhævet og helt gratis. Dash er et helt kursus for at få dig i gang med webudvikling^{(get you started in web development)} . 

Læringsvejen udføres i projektstil ved hjælp af lysbilledshow og Q&A-fora. Efterhånden som du udvikler dig, låser du op for færdigheder som en belønning, ligesom videospil bruger. Der er 5 projekter og 1 sideprojekt, der vil hjælpe dig med at låse op for 82 forskellige webudviklingsfærdigheder. 

Selvom dette ikke vil give dig et job med højere indkomst som webudvikler, vil det få dig i gang som hobbyist, så du kan udvikle disse indkomstoptjenende færdigheder gennem mere formel træning.

Pros	Cons	Languages/Technologies
Project-based	Limited content	HTML
In-browser coding	Hobby level	CSS
Q&A Forums		JavaScript

StudyTonight

Hvis din læringsstil fungerer godt med masser af læsning, er StudyTonight en god mulighed. Uanset hvilket sprog du ønsker at lære, er der sikkert et kursus her til det. Kurserne og tutorials er teksttunge og grundige. Lidt akademisk endda. 

Computerprogrammeringskurser^(Computer) vil ofte gå ind i et sprogs eller teknologis historie til det punkt, hvor versioner af det udlægges med noter. Selvom StudyTonight har en separat YouTube -kanal. Du kan lære at programmere med StudyTonight , men det fungerer måske bedst for folk, der leder efter ressourcer ud over deres formelle studier. Det er annonceunderstøttet, og det kan være distraherende. 

Pros	Cons	Languages/Technologies
In-browser coding	Ads can be distracting	Java
College-level info	Text-based	C and C++
Android app		CSS

JavaTPoint

JavaTPoint er på samme måde som StudyTonight . Der er et bjerg af kurser tilgængelige i snesevis af teknologier og sprog. Der er programmering, DevOps , drafting, AI, blockchain, data mining, soft skills for teknologer og mere. 

Kurserne er godt organiseret, men dette er også et annonceunderstøttet websted. Annoncerne er bestemt distraherende, da mange af dem er animerede. Der er browserbaserede IDE'er^(IDEs) og endda browserbaserede compilere. Men hvis du ikke kan finde et gratis kursus^{(find a free course)} om noget, så finder du det sikkert her.

Mozilla

Mozilla er den organisation, der bringer os Firefox og andre webteknologier. De har sammensat developer.mozilla.org for at hjælpe folk med at blive webudviklere eller finpudse deres færdigheder yderligere. Eller som Mozilla udtrykker det, " Ressourcer^(Resources) til udviklere, af udviklere." 

Det er et velorganiseret, letlæseligt websted, der vil tage dig fra dit allerførste HTML -tag til front-end og back-end webudvikling. Fordi det er Mozilla , får du deres unikke indsigt i, hvorfor ting også skal gøres på en bestemt måde.

W3 skoler^{(W3schools)(W3schools)}

Måske bedsteforælderen til alle online webudviklingskurser, w3schools hævder også at være verdens største webudviklerside. Du ville være hårdt presset for at finde en webudvikler, der ikke lærte noget her. 

Det er heller ikke begrænset til kun webudvikling. Du kan lære server-side teknologier, klassiske programmeringssprog som C++, og endda hvordan man udvikler med Raspberry Pi^{(how to develop with Raspberry Pi)} . Siden er ren, der er masser af browserbaserede ressourcer, og alle på et hvilket som helst niveau kan drage fordel af det. Det er annonceunderstøttet, men annoncerne er ikke så påtrængende som nogle andre websteder.

Pros	Cons	Technologies
Well-respected	None	Too many to list
Browser-based IDE		C++

Google

Nej, vi siger ikke bare gå og søge efter ting på Google . Google har ligesom Mozilla en egeninteresse i at træne nye udviklere og forbedre eksisterende programmørers færdigheder. I modsætning til Mozilla spænder Googles^(Google) interesser vidt og bredt fra webudvikling til AI og alt derimellem. 

Der er en række områder i Googles^(Google) økosystem, hvor vi kan lære stort set alt. Der er Google Digital Garage , Google for Education , Google Developers , Android Developers , og sikkert flere andre, vi savnede. Gå ind på Google og se dig omkring. Hvis du vil lære noget, har de sandsynligvis en computerprogrammeringskursus på det.

Microsoft

Hvis vi skal liste Google , vil vi liste Microsoft . Ligesom Google er der mange forskellige steder i Microsoft - universet at finde deres gratis træning. Det bedste sted at starte er Microsoft Learning . 

Microsoft Learn - platformen adresserer alt fra programmering til systemadministration til Office - apps. Så det kan være lidt udfordrende at finde det, du leder efter, men det er der nok. Læring^(Learning) spilles ved at tildele XP (erfaringspoint) og virtuelle badges og trofæer.

Disse vises på din Microsoft -profil og kan deles via sociale medier som et vidnesbyrd om de færdigheder, du har lært. Tjek også Microsofts Channel 9 ud .

Pros	Cons	Languages/Technologies

edX

Nu er vi på de store navne i massive åbne onlinekurser ( MOOC'er^(MOOCs) ). Kendt for at gøre det muligt for folk at få certifikater og endda grader til mere rimelige priser, har MOOC'er^(MOOCs) som edX også en masse gratis muligheder.

Selvfølgelig giver de gratis muligheder dig ikke et certifikat eller en grad, men du behøver måske ikke et. Hvis du er bekymret for, om du kunne gøre det godt nok til at opnå certifikatet, kan du måske gøre det som den gratis computerprogrammeringsklasse først, og derefter betale for at konvertere det til et certifikat.

Kurserne ledes af lærde i verdensklasse fra skoler i verdensklasse. Stilen minder meget om forelæsningssal, men med mere komfortable stole.

University-level courses	Courses may require prior knowledge	All of them
Degrees and certificates possible for a fee	Degrees have prerequisites and an application process	Python

Coursera

Meget gerne edX, men Coursera har sin egen smag. Jeg har gennemført et par kurser i begge og fandt ud af, at der var en vis forskel i præsentationsstilen, selvom begge har professorer fra nogle af de bedste mulige skoler. 

Min personlige erfaring var, at Coursera var en smule mere uformel end edX, men din oplevelse kan variere. Igen^(Again) kan du fuldføre certifikater eller hele grader mod et gebyr. Ellers er kurserne gratis at tage.

freeCodeCamp

Som deres websted siger: "Siden 2014 har mere end 40.000 freeCodeCamp-kandidater fået job hos teknologivirksomheder, herunder Apple , Google , Amazon , Microsoft , (og) Spotify. ” Kan^(Can) du få en bedre tilslutning end det? 

Vælg mellem over 5.000 tutorials og alt om datalogi, programmering og IT. freeCodeCamp er øverst på næsten alles liste over websteder for at lære at programmere gratis.

Odin-projektet^{(The Odin Project)(The Odin Project)}

På trods af det skræmmende navn er The Odin Project et let fordøjeligt pensum i fuld stack. Hele hjemmesiden og dens kurser er open source og tilgængelige på Github . Det vedligeholdes af et fællesskab af udviklere, hvoraf de fleste lærte at programmere der. 

Ligesom freeCodeCamp fik mange udviklere deres første job efter at have gennemført kurser på siden. De tilbyder endda et kursus kaldet Getting Hired . 

Pros	Cons	Languages/Technologies
Well regarded	None	HTML + CSS
Portfolio-based learning		JavaScript

SkillShare

En lidt anden slags MOOC , SkillShare er en samling af korte og lange kurser skabt af folk, der bare gerne vil dele deres færdigheder. Det er næsten en Coursera eller edX af folk, der ikke nødvendigvis er professorer. På grund af dette kan kvaliteten af ​​computerprogrammeringskurserne variere fra anstændigt til fantastisk. Du kan endda lave dit eget online kursus^{(make your own online course)} og poste det der. 

Der er en masse gratis kurser, og SkillShare har en premium betalt mulighed, der giver dig adgang til flere kurser. De gratis kurser ser ud til at være centreret om webudvikling. Det gør dig måske ikke klar til en karriere som programmør, men det kan hjælpe med at udfylde videnshullerne.

Så mange gratis muligheder, gå i dit eget tempo, betal ikke en skilling, og få endda menneskelig støtte! Der er absolut intet, der forhindrer dig i at blive programmør eller tage dit kodespil til næste niveau. 

Tjek det websted, du synes, og hvis du finder et par stykker, som vi ikke gjorde, vil vi meget gerne høre om det. Fortæl os, om du har gennemført kurser fra nogen af ​​disse sider, og hvad du syntes om dem.

14 Best Sites For Free Computer Programming Classes

Programming used to be about learning to make a program, but now it’s in everything. Data science, machine learning, web development, operations, systems administration…you name it.

We’ll take a look at the best computer programming classes and courses you can find online for free. These computer programming course sites are in no particular order. They’re all great.

Deciding which one is best isn’t for us to do. You need to decide what’s best for your career or hobbyist goals. All of them have at least one of the best programming languages to learn today. We’ll start with the ones you’re less likely to have heard of and add the more popular ones at the end.

Kaggle

If you’re headed in the direction of data science, Kaggle has a series of micro-courses that you’ll enjoy all leading to making you a data scientist. There’s a series of 14 classes, each about 5 to 10 lessons long. The best part, besides being free, is that you don’t need to install any software. 

All of your programming and testing is done right inside of a Kaggle Notebook. What better way to learn Python, SQL, Machine Learning and other data science skills?

Pros	Cons	Languages/Technology
In-browser coding exercises	Only 15 courses	Python

Stanford University

Going to Stanford University isn’t free but their Stanford Engineering Everywhere (SEE) courses are. Published under a Creative Commons license, the SEE material is free and open for reuse. Check the CC license for details. 

Computer programming classes are done university-style and are quite in-depth. If you’re considering getting a degree in Computer Science but aren’t sure if it’s for you, doing these courses will sort that out.

Pros	Cons	Languages/Technologies

Dash by General Assembly

General Assembly is an online learning service with mostly paid courses. But one course is predominantly featured and completely free. Dash is an entire course to get you started in web development. 

The learning path is done project-style using slideshows and Q&A forums. As you progress, you unlock skills as a reward, a lot like video games use. There are 5 projects and 1 side project that will help you unlock 82 different web development skills. 

While this won’t get you a higher-income job as a web developer, it will get you started as a hobbyist so you can develop those income-earning skills through more formal training.

Pros	Cons	Languages/Technologies
Project-based	Limited content	HTML
In-browser coding	Hobby level	CSS
Q&A Forums		JavaScript
		JQuery

StudyTonight

If your learning style works well with lots of reading, StudyTonight is a good option. No matter what language you want to learn, there’s probably a course here for it. The courses and tutorials are text-heavy and thorough. A bit academic even. 

Computer programming classes will often go into the history of a language or technology to the point of laying out versions of it with notes. Although, StudyTonight does have a separate YouTube channel. You can learn to program with StudyTonight, but it might work best for people who are looking for resources in addition to their formal studies. It is ad-supported and that can be distracting. 

Pros	Cons	Languages/Technologies
In-browser coding	Ads can be distracting	Java
College-level info	Text-based	C and C++
Android app		CSS
YouTube Channel		SQL

		Python

JavaTPoint

JavaTPoint is in a similar vein to StudyTonight. There is a mountain of courses available in dozens of technologies and languages. There’s programming, DevOps, drafting, AI, blockchain, data mining, soft skills for technologists, and more. 

The courses are well organized, but this is also an ad-supported site. The ads are definitely distracting as a lot of them are animated. There are browser-based IDEs and even browser-based compilers. But if you can’t find a free course on something, you’ll probably find it here. 

Pros	Cons	Languages/Technologies
Well-organized content	Distracting ads	Too many to list
Huge range of courses		Python
Browser-based IDE		java
Browser-based Compilers		PHP
Text and videos		JavaScript

Mozilla

Mozilla is the organization that brings us Firefox and other web technologies. They’ve put together developer.mozilla.org to help people become web developers or hone their skills further. Or as Mozilla puts it, “Resources for developers, by developers.” 

It’s a well-organized, easy-to-read site that will take you from your very first HTML tag to front-end and back-end web development. Because it’s Mozilla, you’ll get their unique insight into why things should be done a certain way, too.

Pros	Cons	Languages/Technologies
Major authority	Limited to web development	HTML
Browser-based IDE	Mostly text-based	CSS
Well laid-out	Mozilla-centric	JavaScript
Beginner to advanced		Python / Django

W3schools

Maybe the grandparent of all online web development courses, w3schools also claims to be the world’s largest web developer site. You’d be hard-pressed to find a web developer that didn’t learn something here. 

It’s also not limited to just web development. You can learn server-side technologies, classic programming languages like C++, and even how to develop with Raspberry Pi. The site is clean, there are lots of browser-based resources and anyone of any level can benefit. It is ad supported, but the ads aren’t as intrusive as some other sites.

Pros	Cons	Technologies
Well-respected	None	Too many to list
Browser-based IDE		C++

Google

No, we’re not saying just go search out stuff on Google. Google, like Mozilla, has a vested interest in training new developers and enhancing the skills of existing programmers. Unlike Mozilla, Google’s interests range far and wide from web development to AI and everything in between. 

There are a number of areas within the Google ecosystem where we can learn just about anything. There’s Google Digital Garage, Google for Education, Google Developers, Android Developers, and probably several others we missed. Get into Google and look around. If you want to learn something, they probably have a computer programming class on it.

Pros	Cons	Languages/Technologies

Microsoft

If we’re going to list Google, we’re going to list Microsoft. Like Google, there’s a lot of different places in the Microsoft universe to find their free training. The best place to start is Microsoft Learning. 

The Microsoft Learn platform addresses everything from programming to systems administration to Office apps. So it can be a bit challenging to find what you’re looking for, but it is probably there. Learning is gamified by awarding XP (experience points) and virtual badges and trophies.

These are displayed on your Microsoft profile and can be shared through social media as a testament to the skills you’ve learned. Also, check out Microsoft’s Channel 9.

edX

Now we’re onto the big names in massive open online courses (MOOCs). Known for enabling people to get certificates and even degrees for more reasonable prices, MOOCs like edX also have a lot of free options.

Of course, the free options don’t get you a certificate or degree, but you might not need one. If you’re concerned about whether you could do well enough to earn the certificate, maybe do it as the free computer programming class first, then pay to convert it to a certificate.

The courses are led by world-class scholars from world-class schools. The style is a lot like lecture hall learning, but with more comfortable chairs.

Pros	Cons	Languages/Technologies
University-level courses	Courses may require prior knowledge	All of them
Degrees and certificates possible for a fee	Degrees have prerequisites and an application process	Python
Text and video mixed		Java

Coursera

Very much like edX, but Coursera does have its own flavor. I’ve completed a few courses in both and did find there was some difference in the presentation style, even though both feature professors from some of the finest schools possible. 

My personal experience was that Coursera was a bit more informal than edX but your experience may vary. Again, you can complete certificates or entire degrees for a fee. Otherwise, the courses are free to take.

freeCodeCamp

As their site says, “Since 2014, more than 40,000 freeCodeCamp graduates have gotten jobs at tech companies including Apple, Google, Amazon, Microsoft, (and) Spotify.” Can you get a better endorsement than that? 

Choose from over 5,000 tutorials and everything computer science, programming, and IT. freeCodeCamp is at the top of almost everyone’s list of sites for learning to program for free.

Pros	Cons	Languages/Technologies

The Odin Project

Despite the intimidating name, The Odin Project is an easy to digest full-stack curriculum. The entire website and its courses are open source and available on Github. It’s maintained by a community of developers, most of whom learned to program there. 

Like freeCodeCamp, many developers got their first job after completing courses on the site. They even provide a course called Getting Hired. 

Pros	Cons	Languages/Technologies
Well regarded	None	HTML + CSS
Portfolio-based learning		JavaScript

SkillShare

A slightly different kind of MOOC, SkillShare is a collection of short and long courses created by people who just want to share their skills. It’s almost a Coursera or edX by people who aren’t necessarily professors. Because of this, the quality of the computer programming classes can range from decent to great. You could even make your own online course and post it there. 

There are a lot of free courses, and SkillShare does have a premium paid option that allows you to access more courses. The free courses appear to be centered on web development. It might not get you ready for a career as a programmer but it can help fill in the knowledge gaps.

Pros	Cons	Languages/Technologies
