For who are CS self-taught, where is the guide?
I have not attempted this but there are many Computer Science study guides to be found on the web, a quick google search can provide a template for free online books, and courses. I hear that CS50/x is always a good first step, you will also need to do math, learn algorithm development and data structures…
So this looks like a helpful link, not too overwhelming i hope, this is a difficult goal and a long one and takes about 2 years on average to complete (because life gets in the way)
Good Luck and Happy Coding
