According to 400 Devs, what are the best sites for learning code?!

I asked on Twitter "What is your favorite site to learn programming?" and I got almost 400 answers. Freecodecamp.org is an excellent choice for many people as it covers many aspects of programming. If a site doesn't belong to the Most Common/Very common section it doesn't mean that it's not good! Work with the sites that best suit your needs!
