When Should You Reach for ESLint?

The Basics

Integrating ESLint with editors like VS Code surfaces errors the moment you write the code, before you ever commit.

When It Actually Makes Sense

ESLint is a static analysis tool for JavaScript/TypeScript that catches problematic patterns before code ever runs. ESLint rules are fully configurable, letting teams define custom rules that match their own coding style. The right call usually depends on your project's scale, team, and real needs — not just a tool's popularity.
