Prettier is an opinionated code formatter that offers support for a wide range of programming languages and formats, including JavaScript, JSX, Angular, Vue, TypeScript, CSS, and HTML, among others. It is designed to remove all original styling and ensure that the outputted code conforms to a consistent style. One of the key features of Prettier is its ability to handle long lines of code.

It takes your code and reprints it from scratch, taking into account the line length. This means that even if you have a function call with multiple parameters that stretches the line length, Prettier will automatically wrap the code for you, making it more readable and maintainable. Prettier enforces a consistent code style across your entire codebase by parsing away the original styling and re-printing the parsed AST with its own rules.

This ensures that the code formatting won't affect the Abstract Syntax Tree (AST) of your code. If you want to learn more about Prettier and its benefits, there are several conference talks available as great introductions. Prettier is highly regarded by the developer community and has gained popularity for its ease of use and ability to improve code readability.
