Prettier
Prettier is a tool that helps developers make their code look clean and consistent. Think of it like an automatic formatting assistant that arranges code in a neat, standardized way. When developers work together on projects, everyone might have different styles of writing code. Prettier eliminates these differences by automatically reformatting the code to follow the same style rules. This is similar to how Microsoft Word might automatically fix formatting in a document. It's widely used in modern web development to save time and maintain consistent code appearance across teams.
