They offer courses supported by YouTube videos. They also offer certifications for subjects like JavaScript Algorithms and Data Structures, Backend Development and APIs, and Machine Learning with Python.
Lots of free courses on tons of subjects including conputer science and mathematics.
oh, I also have to mention codewars. That site was absolutely instrumental in giving me the confidence that maybe I could actually learn this shit. The first kata I did was as simple as "convert the boolean to a string," but that was exactly what I needed! I also like how it's less corporate than leetcode.
Try scrimba.com, it's an interactive lecture that has labs requiring input to proceed.
For someone looking to learn js. This is probably the best way to start.
JavaScript, my nemesis. I tried it many years ago, and I got the feeling of something so… ethereal, disconnected, and at sometimes random, that I never find the time to get to know it. And I probably should, may as well try this, thanks.
Recently I discovered Harvard's CS50 series of classes.
A really excellent way to learn programming in a class structure without actually going out to classes and having hard deadlines.
