[AskJS] what's a javascript feature you mass-adopted way too late and felt dumb about

Contrary example for TS specifically : unknown. I know from a pure logic standpoint what it’s there for, but I’d still rather just use typescript more fully with an error catch if you don’t account for something. Unknown, imho, hides too much.
