ESLint Study Portal

TL;DR

A strict ESLint config treats warnings as errors and leans on --fix to auto-correct the mechanical stuff (var→const, ==→===, quote/semicolon style, import order) while flagging the issues that need a human decision (no-explicit-any, unused vars, floating promises). The split between auto-fixable and manual rules is what keeps the zero-warning policy practical instead of punishing.
