Spent 6 hours debugging a missing semicolon in JavaScript

I was working on a basic calculator project for a course I'm taking. Everything looked fine in the code, but the whole thing just wouldn't run. I checked my loops, my variables, even rewrote a whole function from scratch. After 6 hours of staring at it, I finally noticed I forgot a semicolon after a return statement inside an if block. It was literally one character. Has anyone else spent way too long on a dumb syntax error like this?

Oh man, that's rough, I've totally been there! What finally clicked for me was using a linter like ESLint - it catches those sneaky missing semicolons and other little errors right away. Now I just run it as I type so I don't waste hours hunting for one dumb mistake. It's saved me so much time, you wouldn't believe it. Seriously, set it up in your editor and you'll never look back.
