When you’re building an app, you’ll always have a code editor, a terminal, and a browser open at the same time. Each one has a different job, and you’ll bounce between them constantly. Understanding what each window is for — and which one a problem is coming from — is one of the most practical skills you can pick up early.
In this lesson we’ll tour all three windows, spend extra time making the terminal feel approachable, and cover the tiny set of commands you actually need to get started.
- The three windows every builder has open: editor, terminal, browser
- Why the terminal isn’t scary and how it fits into your workflow
- The short list of commands you’ll actually use day to day
- How to figure out which window a problem is coming from when things break
