Typed Linting ⚡️
ESLint is a linter. It runs a set of rules to find likely problems and suggested fixes to improve your code.
TypeScript is a language and a type checker. The language adds syntax for types to JavaScript.
The type checker analyzes code to find mismatches between uses of values and types.
typescript-eslint is necessary for JavaScript tools such as ESLint to work with TypeScript's new syntax.
It also adds lint rules for TypeScript, including many that use the power of types to better analyze code.
