Self-Study Coding Checklist
It's not the easiest thing to teach yourself how to code, and those who do often miss certain topics and then struggle for years not understanding why. That's the reason I created this checklist. You can go through and check which topics you're already familiar with and see which one's you still need to learn or work on. I hope it helps you on your self-taught journey!
The checklist is not a complete list of every topic you should be familiar with. Rather, it's a collection of those topics that I think you might have missed while teaching yourself how to code.
The state of the checkmarks is saved as cookies in your browser.
