@itchie-tatsumi.bsky.socialこういう処理時間の測定には、performance.now()が向いています。こちらはシステム時計の調整の影響を受けず、値が減らない単調時計（モノトニッククロック）を基準にしています。ミリ秒未満の細かい計測も可能ですが、分解能は環境によって異なります。
今が何時なのかを知るならDate.now()、どれだけ時間が経過したかを測るならperformance.now()。用途が違うんですね。
単純な引き算なのに、使う時計によっては結果がおかしくなるという、ちょっとした落とし穴です。

My GIF passed a frame-count check but had one distinct decoded image. FFmpeg's framemd5 exposed it.

@kashishpal.comI was rendering GitHub users with `fetch()` + `useState`.
Then my UI rendered infinitely. 💀
`fetch()` → `setState()` → re-render → `fetch()`...
That’s when `useEffect` clicked.
Side effects, dependency arrays, and cleanup finally make sense. 🚀
