决定哪一个是最好的不是我们要做的。您需要确定最适合您的职业或业余爱好者目标(career or hobbyist goals)的方法。他们都拥有至少一种当今最好的编程语言(best programming languages to learn today)。我们将从您不太可能听说过的那些开始，并在最后添加更流行的那些。
它也不仅限于 Web 开发。您可以学习服务器端技术、C++ 等经典编程语言，甚至可以学习如何使用 Raspberry Pi 进行开发(how to develop with Raspberry Pi)。该网站很干净，有很多基于浏览器的资源，任何级别的人都可以从中受益。它支持广告，但广告不像其他一些网站那样具有侵入性。

不，我们并不是说只在Google上搜索内容。与Mozilla一样，(Mozilla)谷歌(Google)在培训新开发人员和提高现有程序员的技能方面有着既得利益。与Mozilla不同，谷歌(Google)的兴趣范围很广，从Web 开发(web development)到AI 以及(AI and everything)介于两者之间的一切。
与MOOC(MOOC)略有不同的是，SkillShare是由只想分享技能的人们创建的短期和长期课程的集合。它几乎是那些不一定是教授的人的Coursera 或 edX 。(Coursera or edX)正因为如此，计算机编程课程的质量可以从不错到很好。您甚至可以制作自己的在线课程并将其发布(course and post)到那里。
14 Best Sites For Free Computer Programming Classes
Programming used to be аbout 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.
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?
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.
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.
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.
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.
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.
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.

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.

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.
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.

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.

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.
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.
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.
