🗺️ Develop Locally:
claspallows you to develop your Apps Script projects locally. That means you can check-in your code into source control, collaborate with other developers, and use your favorite tools to develop Apps Script.

clasp (Command Line Apps Script Projects) is a CLI that allows you to start, write, test, and deploy Apps Script projects from any text editor you want.
