Example of minified JavaScript:

Before:

function calcAverageDiff(arr) {
  let sum = arr.reduce((acc, curr) => acc + curr, 0);
  let avg = sum / arr.length;
  let diffs = arr.map(num => num - avg);
  return arr.map((num, index) => [num, diffs[index]]);
}

function calcAverageDiff(arr) { let sum = arr.reduce((acc, curr) => acc + curr, 0); let avg = sum / arr.length; let diffs = arr.map(num => num - avg); return arr.map((num, index) => [num, diffs[index]]) }
