Spent 6 hours debugging a missing semicolon last night

I was following a JavaScript tutorial from 3 years ago and couldn't figure out why my loop wouldn't run. Turns out I forgot a single semicolon on line 47 in VS Code. Has anyone else wasted a whole evening on something this tiny?

Used to roll my eyes at people saying semicolons matter that much in JS. Then I spent four hours tracking down a bug that turned out to be ASI failing on a return statement. Now I just put them everywhere automatically, even in languages that dont need them. Its crazy how one little character can just eat your whole evening like that.

That reminds me of the time I spent an hour debugging a missing comma in a config file, so I feel your pain.
