• Dynamically setting keys in objects (i.e. keys are not hard-coded).
• Using Array iteration methods.

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.
  • Using Javascript Snippets to execute and save your scripts.
• 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").
