Best Online Course Providers

01. Khan Academy

• Free and paid

Khan Academy is very straightforward and offers quizzes

Khan Academy is a free online school that's not just focused on coding – there are a wide range of courses on offer, from economics to arts and humanities. Under the Computing section, you'll find courses on computer programming, computer science, coding and animation, all of which are broken up into specific sub-sections.
What's interesting with Khan Academy is that you hear someone talking while they write the code, which feels natural, like you're sitting down with someone. The courses were straightforward, easy to follow and you can then transfer the concepts to the simple exercises.
Sometimes, there are mini-quizzes following a demo, which help you think about things conceptually and understand what the code is doing a little better.

02. Hack Design

• Free and paid

This is a great source of aggregated content

The 'courses' here are just collections of aggregated content, whether that's blogs, books, games, tutorials or videos, from around the web. There isn't anything to ‘complete' by way of tasks, but if you're after some resource recommendations to help you learn more about a specific part of design, this is a good place to turn.
There are also tool lists with recommendations from people who use them. This is an excellent catalogue of design resources for all levels. It offers great introductory content for beginners and more advanced techniques for those who do this full-time.

03. Udacity

• Large selection of free courses
• Nanodegrees from around €200 (approx $250)

Udacity covers a huge array of technical subjects

Udacity offers robust guides to many different topics, with seriously advanced courses on everything from robotics to design theories in everyday life. There's a big selection of free courses on offer here – and not just basic ones, either, but across all skill levels.
Alternatively, Udacity has a range of 'nanodegrees', which cover in-demand skills. Current courses on offer include Design Sprint Foundations and VR Developer. Prices and lengths of course vary dramatically, but the cheapest courses start at around €200.
All courses are summarised before you even begin, outlining the difficulty level, why the course is important, any prerequisites for taking it, and the project you will complete at the end. This means you can easily scan through and choose what suits you best.

04. Code School

• $29/mo 
• 15 free courses available

Code School offers some free courses

Of all the tools we dug into, Code School – owned by Pluralsight – was one of the best. Not only does the site look great, but it offers quality content and a great student experience. You can follow a 'path', which will guide you through a succession of different courses, or you can opt for a single course on its own.
The videos are quirky and fun in an after-school special kind of way, which is a refreshing break from typically dry video tutorials. It's like watching Bill Nye explain it, which is to say, comforting. After viewing a video, you work on your own tasks – relating back to the video if required. If you get really stuck you can 'buy' answers with points you've earned from other classes.
Code School offers 15 introductory courses for free, so you can try it out for size, or you can buy a monthly subscription for $29/month. If you're looking to splash a few bucks on a learning tool, we would recommend spending your money here.

05. Simpliv

• Large selection of free and paid courses
• Nanodegrees from around $12

Online learning platforms such as Simpliv are completely changing the face of the education landscape for better.

One interesting thing about this online code school is the Code Avengers Junior section. This teaches children basic programming and computer literacy skills, via gamified courses.
