The comprehensive list of learn-to-code websites
September 19, 2016

Over the past three years, I have worked with hundreds of librarians, staff and educators to launch code clubs – weekly meetings where people learn to code in an informal, self-guided way. The facilitators of these code clubs differ in many ways – appearance, interests, background, and job description. But they share one surprising characteristic: they are not computer programming experts!

You might wonder how thousands of kids, teens and adults could be learning to code without the experienced oversight of a professional software developer.


The short answer is that all the content needed to learn to code is available for free on the internet. Gone are the days of verbally transmitting information from the teacher to the student. Instead, learners find the information they need in the form of websites, blog posts, videos, articles, tutorials, and interactive exercises. Not only do these tools allow each student to learn what they want at the pace they are comfortable with, but they also lead to much more efficient learning than the traditional lecture format.

But many people don’t know where to find these amazing resources. Look no further! After years of trial and error, and collaborations with scores of inspirational and informative people, we have compiled this list of the best learn-to-code resources available on the internet.
