Data Types Practice

This exercise will give you the opportunity to practice working with the fundamentals of JavaScript covered in class.


  • Fundamental JavaScript
  • Numbers, Strings, and Booleans
  • Variables
  • Arrays
  • Array Methods


  1. Fork and clone this repository.
  2. Change into the new directory.
  3. Fulfill the listed requirements.

Starter code is available in lib/challenge.js. You are required to turn in your submission by making a pull request on the original repository.

Open index.html in your browser, and utilize console.log to help test your work.

Make one commit for each prompt


There are a series of prompts inside of the starter code found in lib/challenge.js. Work through all of the prompts. Each prompt is in the form of a JavaScript comment. Write your code to solve the prompt after the comment.

Some prompts will require you to practice researching methods we did not learn in class.

Tip: Use console.log to test your work, but delete those statements when you finish working on the prompt, before moving on to the next one! Otherwise, you'll end up with a lot of clutter in your console and it will be hard to debug the prompt you're currently working on.

You are required to make one commit after each prompt
