## What it is
Prettier is an opinionated code formatter that parses code and re-prints it with consistent style rules, supporting JavaScript, TypeScript, CSS, HTML, Vue, Angular, GraphQL, Markdown, YAML, and more via plugins. It can run in editors on-save, in pre-commit hooks, or in CI to enforce a uniform codebase style.

## Use cases
- format javascript and typescript code consistently
- enforce code style across a team without manual review comments
- format css, html, vue and angular templates
- run formatting in ci to check style compliance
- format markdown, yaml and json files
- add a pre-commit hook to auto-format staged files
- integrate formatting into vscode on save

## When to choose
- you want zero-config, opinionated formatting across many languages
- your team argues about code style and wants to end the debate
- you need consistent formatting in editors, git hooks, and CI
- you work with mixed web codebases (js, ts, css, html, markdown)

## When to avoid
- you need highly customizable style rules rather than opinionated defaults
- you want a linter that catches bugs, not just formatting
- you only need formatting for a language without a prettier plugin
