Y'all thought I wouldn't take the opportunity to nerd out about a JS internals thing? JSON.stringify improvements may not sound exciting, but to me....yeah. Enjoy.

LMAO 0:56 When parsing the JSON literal (very likely using some compiled lib underneath) is faster than defining it, truly a JS moment

3:13 — I once seen a competition task where you had to implement your own "memoization" (basically implement a function that creates a wrapped over another function, and if input arguments like given were already passed, return cached result instead of passing it to the actual function)... Guess what was the recommended solution? Yeah, just JSON.stringify the entire arguments array and look it up in a cached results set.
