Array Champion 3000

It’s time to work out those array muscles and exercise your JavaScript skills that you’ve been developing!

  1. First, open up the MDN web docs for arrays.

  2. Next, download the starter HTML file and put it in your cs343/dev directory, inside a new folder called prep4 or something similar.

  3. Open it through VS Code. You should see a few arrays and eight numbered comments.

  4. Your goal is to use different array methods and write callback functions to solve each of the little exercises and become an array CHAMPION!

    • Pro tip: The MDN web docs listed above are your best friend here
    • Make sure your variable names to store the results match those provided in the file!

  5. When you’re done, submit your arrays.html to the corresponding Gradescope assignment.
