Precourse: Recursion

A recursive function is one that calls itself 📞. In this assignment you will use recursion to solve three problems.

Objectives

In this assignment you will use JavaScript and recursion to:

• create possible hands 🖐 for Rock, Paper, Scissors.
• traverse the DOM and get elements by their class name.
• turn JavaScript values into JSON strings.

Instructions

• Fork 🍴 and clone this repository following the Code Chrysalis git flow instructions.
• Open the index.html file in your browser. You will see a list of failing tests.
• Commit your work often.
• When you have completed all the tasks, follow the Code Chrysalis git flow instructions to create a pull request.

Basic Requirements

Write code in the src/rockPaperScissors.js, src/getElementByClassName.js, and src/stringifyJSON.js files to make the tests pass.

• rockPaperScissors: 🤘 📄 ✂️ Generate permutations of the game Rock, Paper, Scissors.
  • Read blog posts on recursion: Part 1 and Part 2
• getElementByClassName: A practical instance of recursion. The DOM is a 🌳 tree structure and recursion is an efficient way to traverse it.
  • See links provided in Resources for some help
• stringifyJSON: Also a very practical use of recursion. We will be recreating the JSON.stringify method, which converts a JavaScript value to a JSON string.

Resources

• Watch Fun Fun Function's Recursion video
• Useful for getElementsByClassName
  • JavaScript Info: DOM Nodes
  • JavaScript Info: Walking the DOM
