About Code Formatter

Code Formatter uses Prettier under the hood to apply consistent style to JavaScript, TypeScript, JSX, TSX, CSS, SCSS, and several other languages with a single click. This eliminates arguments about brace style, semicolons, and quote style by enforcing one canonical format. It is ideal for cleaning up code before a code review or when onboarding to a project that uses Prettier.
