It works in three steps: parsing to AST, transforming to an intermediate document tree with opinionated rules, and printing with optimal line breaks. Unlike ESLint, Prettier handles stylistic formatting rather than linting for bugs, and the two tools complement each other. Benefits include eliminating style debates in code reviews, reducing formatting fatigue, lowering the barrier for newcomers, and ensuring codebase consistency. It supports ES2017, TypeScript, JSX, CSS, SCSS, GraphQL, and more. Setup is simple via editor plugins, npm local dependency, or pre-commit hooks. ## Full article daily.dev links to this article rather than hosting it.
