We are required to write a JavaScript function that takes in an array of Numbers (positive and negative numbers).
The function should return the highest product of two adjacent elements of the array.
For example −
If the input array is −
const arr = [-23, 4, -3, 8, -12];
Then the output should be −
const output = -12;
and the two elements are 4 and -3
Example
const arr = [-23, 4, -3, 8, -12]; const adjacentProduct = (arr = []) => { let first = 0; let second = 0; let res = Number.MIN_SAFE_INTEGER; for (let i = 0; i < arr.length; i++) { first = arr[i]; second = arr[i + 1]; if (first * second > res) { res = first * second; }; }; return res; }; console.log(adjacentProduct(arr));
Output
This will produce the following output −
-12
