  Write a function `diffArrayLen(arr1, arr2)` that takes two arrays. The
  function should return true if the arrays have different lengths. The
  function should return false otherwise.
  
  Examples:
  
  let a1 = ['a', 'b', 'c'];
  let a2 = ['w', 'x', 'y'];
  let a3 = [1, 3, 7, 4];
  
  diffArrayLen(a1, a2); // => false
  diffArrayLen(a1, a3); // => true
  ***********************************************************************/
  
  function diffArrayLen(arr1, arr2) {
    return arr1.length !== arr2.length;
  }
  
  module.exports = diffArrayLen;
