JavaScript

Imagine you have the following function, which is a function that takes a really long time to square a number. It takes a number to square, and a callback that it will eventually call with the result of squaring that number.

function slowSquare(x, callback) {
  setTimeout(function() {
    callback(x * x);
  }, 500);

Client Services Code Exercise

Using HTML, CSS, and JavaScript, you will create a tool that allows a user to drill down through a tree of categories and select a final category. The taxonomy data is represented as a tree of categories. A category can have any number of children. A category with no children is considered a selectable category (categories with children should not be selectable).

The taxonomy data is located at https://gist.github.com/5527862
