The web in hyper speed: Boosting performance with memoization
summary
Claim: memoization cuts repeated pure-function work dramatically — a demo goes from ~2.2ms to ~0.17ms (about 95% speedup) and a generic wrapper version runs ~0.45ms. Implements a JS cache pattern using console.time for measurement, shows examples on a discount function and Fibonacci recursion, and maps the idea to React’s useMemo hook. The thing built is a generic memoize wrapper around functions, it runs successfully and reduces redundant computation.
