Can we talk about how one missing semicolon ate my entire Saturday?
I was building a little tip calculator from a YouTube tutorial last week and got stuck for 3 hours on a page that would not show any numbers, just a blank screen. I finally opened the console and saw the error pointing to line 42, where I had typed 'let tip' instead of 'let tip;' and the whole script stopped right there. Does anyone else lose an entire afternoon to one tiny typo, and is there a habit that helps you catch these faster?
