title: How to get an array of values based on an array of indexes?
body: <p>I have a set of two arrays. One contains some fruit values as strings, the other one contains some random numbers. Here I considered the number arrays are the indexes of the fruits array. How to get a new array of fruits given the numbers in the index array?</p>
  
  <p>Sample code:</p>
  
  <pre><code>var resultArr = [];
  var fruitier = ["apple", "orange", "grapes", "pineapple", "fig", "banana", "jackfruit", "pomegranate"];
  var indexArr = [0, 2, 4];
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>resultArr = ["apple", "grapes", "fig"];
  </code></pre>
