Javascript Interview Question Array Get the third greatest number

Introduction

Write a method that takes an array of numbers in.

Your method should return the third greatest number in the array.

You may assume that the array has at least three numbers in it. 

function third_greatest(nums) {
  //your code/*from  w  w w  .jav  a2  s  . c o  m*/
}

// These are tests to check that your code is working. After writing
// your solution, they should all print true.

console.log( third_greatest([5, 3, 7]) === 3);
console.log( third_greatest([5, 3, 7, 4]) === 4);
console.log( third_greatest([2, 3, 7, 4]) === 3);





function third_greatest(nums) {
  nums = nums.sort();
  var thrdGreatest;
  thrdGreatest = nums[nums.length-3];
  return thrdGreatest;
}

// These are tests to check that your code is working. After writing
// your solution, they should all print true.

console.log( third_greatest([5, 3, 7]) === 3);
console.log( third_greatest([5, 3, 7, 4]) === 4);
console.log( third_greatest([2, 3, 7, 4]) === 3);
