Executing your code

There are a number of options for running/executing your code. They all have their uses, so we encourage you to learn all of them:

  • From the browser:
    • Using the Chrome Developer Console
      • Tip: Use ↑ and ↓ to cycle through your code history. Pressing → selects the current suggestion. If there’s a single suggestion, Tab to select it.
  • From the command line:
    • Using the Node REPL / Shell
      • Tip: Type .exit to quit. Use ↑ and ↓ to cycle through your code history.
    • Using the node some-file.js command
      • Tip: Use ctrl + c (shortcut) to quit "hanging" programs. And make sure to console.log("your output").
