Using the Math.max() Function

This small exercise helped me get more familiar with using Math.max().

The Question

// "Given an array of integers, find the pair of adjacent elements that has the largest product and return that product."
// For inputArray = [3, 6, -2, -5, 7, 3], the output should be
adjacentElementsProduct(inputArray) = 21.
// 7 and 3 produce the largest product.
// from CodeFights

My Thought Process

// Use a for loop to run through the array.
// Take the product of each adjacent element.
// Push the product to a new array. 
// Run a separate function on the new array to output the highest integer.

1) After writing my pseudocode I opened Chrome’s JavaScript Console (Opt + Cmd + J on Mac) and originally tried this:

function adjacentElementsProduct(inputArray) {
  for (var i = 0; i < inputArray.length; i++) {
  let ans = inputArray[i] * inputArray[i+1];
  console.log(ans);  
  }
}
// let ans = inputArray[i] *…
