What you're building
A bit.ly-style tool that takes long URLs, generates short random codes for them, stores the mapping in localStorage, and lets you click the short link to simulate a redirect — complete with a click counter per link. There's no real server, but the mechanics (hashing, lookup tables, redirect simulation) are the same ones real URL shorteners use.
