Hi Darleen,

I'll do a little bit with the adjacent elements question and leave the difference between any two elements to you.

So this is the question:

Largest gap between consecutive elements in an array

Write a function that takes as input an array, and returns the largest difference between any two adjacent elements.

If we break that down we want to find the differences between all the adjacent elements in the array and save the largest difference to a variable that we will return from the function.

The pieces of code that we will need are a function, a variable to store the largest difference, a for loop that will iterate over the adjacent element pairs of the array, a return statement that will return the largest difference.

Note:
What happens if the first element is 4 and the second element is 11. 4 - 11 is -7. It's going to be hard to make a conditional test with both negative and positive numbers.

See this link for a method from the Math built-in object called abs() that will always return a positive number value: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/abs

var largestDiff = function(array) {
    var bigDiff = // what should we put here to get the difference between the first element of the array and the second element of the array

    // iterate over each element of the array minus one (why minus one?)
    for (var i = 0; i < array.length - 1; i++) {
      var difference = // what should we put here to get the difference between the current element value and next's value
      if (bigDiff < difference) {
        bigDiff = difference;
      }

      return bigDiff;
    }
}
