Udemy bills itself as an online learning marketplace, hosting 130,000+ user-created courses on all kinds of topics (including over 2,000 coding-related classes).

I recommend checking out CS Dojo, TheNetNinja, and Harvard’s CS50 YouTube channel. If you don’t have time to search for a perfect coding video or channel, you can also check out LinkedIn Learning’s vast video library for vetted and professional-looking tutorials. While the service’s $30/month subscription fee is nothing to sneeze at, you can binge-watch an unlimited amount of content and topics—making LinkedIn Learning a better deal than other on-demand online classes that come with annoying restrictions.

You probably can’t go wrong with the free Introduction to Computer Science from Harvard University.
