Terminal

A text-based interface for interacting with your computer's operating system by typing commands. Also called the command line or CLI (Command Line Interface).

Many developer tools only work via the terminal. Knowing basic commands (cd, ls, npm install, git push) lets you follow tutorials, manage projects, and work with developers without confusion.

A founder opens her terminal, navigates to her project folder with cd, runs npm run dev to start her app locally, and sees it at localhost:3000 in her browser.
