Random numbers are useful for creating random behavior.

JavaScript has a Math.random() function that generates a random decimal number between 0 (inclusive) and 1 (exclusive). Thus Math.random() can return a 0 but never return a 1.

Note: Like <a href="/learn/javascript-algorithms-and-data-structures/basic-javascript/storing-values-with-the-assignment-operator" target="_blank" rel="noopener noreferrer nofollow">Storing Values with the Assignment Operator</a>, all function calls will be resolved before the return executes, so we can return the value of the Math.random() function.

--instructions--

Change randomFraction to return a random number instead of returning 0.

--hints--

randomFraction should return a random number.

assert(typeof randomFraction() === 'number');

The number returned by randomFraction should be a decimal.

assert((randomFraction() + '').match(/\./g));

You should be using Math.random to generate the random decimal number.

assert(__helpers.removeJSComments(code).match(/Math\.random/g).length >= 0);

  return 0;

function randomFraction() {
  return Math.random();
