Ah, that does make more sense, and is a language feature I've often thought about. It's usually just a pattern and not a first class feature, but with many problems as a result (many of which React itself encounters). Lots of use of context managers in Python are for accomplishing this. Smalltalk error handlers are like this (different than try/catch). Or Scheme's with-output-to-file... I got the sense that variables that start and end with stars in Common Lisp are used for this, but I was never clear if it was convention or an actual language feature. I think I'd like it in React too if they just hadn't tried to be so clever.
