How joelleonardt/codingcamp-6july26-joelleonardt works
This is a client-side expense tracker with budget visualization. Users enter and validate transactions, which are saved in browser storage; the app then reloads state, computes totals and summaries, and renders the interface. Users can also sort transactions, set a spending limit, and view category and monthly summaries. The README offers no architecture detail, and the sampled JavaScript is incomplete, so uncertain internal wiring is omitted.
