Multi-Language Code Beautification
Code beautification (pretty-printing) reformats source code to follow consistent style conventions: indentation, spacing, line breaks, and bracket placement. Different languages have different conventions and tools. Prettier is the most popular multi-language formatter, supporting JavaScript, TypeScript, CSS, HTML, JSON, YAML, Markdown, and more from a single tool.
