Learn to code: resources for every programming language

While not everyone needs or wants to become a programmer, the benefits of code literacy extend beyond the ability to build websites—including improved abstract thinking and problem-solving skills. And as more of our lives run on software, it only makes sense to learn a bit about the languages that power our world. The need to learn to code has never been more pressing.

Luckily, there has never been a better time to learn to code. There are tons of high-quality, interactive resources out there, and more are being made available every day. Though this list is by no means exhaustive, below I’ve assembled some of the best free and paid resources for learning every programming language.
