Chrome DevTools Performance Panel: Analyzing Code Execution

Open the Performance panel in Chrome DevTools for the first time and it looks like someone spilled a box of crayons across your screen. Dozens of colored bars, half a dozen tracks, three tabs at the bottom that all seem to show the same thing but slightly differently.

I’ve seen senior developers reach for localStorage for everything — auth tokens, shopping carts, even megabytes of API responses — simply because it’s the one they know. That’s not always wrong, but it’s rarely the best choice. Let’s actually go through what each of these mechanisms does, where you’d find it in DevTools, and — more importantly — when you should reach for it instead of the other six options sitting right next to it.
