Array Maximal Adjacent Difference

Given an integer, find the maximal absolute difference between any two of its adjacent elements. Example
For Input: inputArray = [2, 4, 1, 0] the output should be arrayMaximalAdjacentDifference(inputArray) = 3
Solution: 20
console.log(double(10,2)) => 40

function arrayMaximalAdjacentDifference(inputArray) {
  let maxDiff = Math.abs(inputArray[0] - inputArray[1]);
  
  for(let i = 0; i< inputArray.length; i++) {
    let absoluteDiff = Math.abs(inputArray[i-1]-inputArray[i]);
    
    maxDiff = absoluteDiff > maxDiff ? absoluteDiff : maxDiff;
  }
  
  return maxDiff;
}

console.log(arrayMaximalAdjacentDifference([2,4,1,0])) => 3

We have a function called arrayMaximalAdjacentDifference with parameters inputArray and local variable maxDiff = Math.abs(inputArray[0] - inputArray[1]);

Then we iterate using for loop and create another temporary variable absoluteDiff = Math.abs(inputArray[i-1]-inputArray[i]);

We check if maxDiff is equal to absoluteDiff lower than maxDiff and if true we return absoluteDiff else maxDiff;

In the end we return maxDiff
