The problem is likely that you never started at the basics, and never learnt what you needed to solve your problem. You also have a clear idea, and try to build all of it at once. A common mistake.
You want to build a todo app?
Fine.
You are going to need to have some website. Cool. You only need to google how to display “todo list” on the page. 5 minutes of html will teach you that.
Then a list. Again 5 minutes of html.
Then add an entry. 10 minutes of JavaScript.
You don’t need react. You don’t need to know closures. You don’t need lambdas. Nobody needs tailwind ever.
Conversely, I think they probably have a good grasp of the basics considering they've been through them so many times. The real thing they lacked was a reasonable idea. I find a lot of early engineers have this problem where the only things they actually want to build are too complex for their skills. So they end up stuck in this 'Tutorial Hell' loop hoping to acquire those skills until they actually reason down to a project that fits their skill level and go from there as OP did here.
