Using Math.min() on an Array

To find the lowest number in an array, you can utilize Math.min.apply.

Example

function myArrayMin(arr) {
return Math.min.apply(null, arr);
}

Math.min.apply(null, [1, 2, 3]) is identical to Math.min(1, 2, 3).

Using Math.max() on an Array

To identify the highest number in an array, you can employ Math.max.apply.

Example

function myArrayMax(arr) {
return Math.max.apply(null, arr);
}

Math.max.apply(null, [1, 2, 3]) is the same as Math.max(1, 2, 3).
