I've been working professionally with React and JavaScript for more than 8 years and I compiled all my knowledge into 100+ infographics and 70+ video tutorials just like this one. Check them out ↓

Don’t follow this advice. It makes your code less readable, it confuses other developers and your IDE. This level of abstraction is not helping anybody. Just use early return.

Nice, but wouldn’t it be easier to read code with if(!condition) throw new Error(“some message”) Instead of creating abstraction?

Just use fail fast/ early return and you’ll avoid that level of abstraction.

I don't like this - you're hiding important control flow inside deeply nested functions. The caller must now know that implicitly your functions use exception control flow and throw on certain conditions (also hidden). Guards (if not x return) are usually better.

Dude an "any" wrapper function? That's scares the shit out of me

💯 This makes it super hard to read the code

"early bail" or "early return" is far better terminology
