What is TypeScript?
TypeScript is a syntactic superset of JavaScript which adds static typing. This means that TypeScript adds syntax on top of JavaScript, allowing developers to add types.
Next.js comes with built-in TypeScript, automatically installing the necessary packages and configuring the proper settings when you create a new project with create-next-app. To add TypeScript to an existing project, rename a file to .ts / .tsx. Run next dev and next build to automatically install the necessary dependencies and add a tsconfig.json file with the recommended config options.
