Find the min/max element of an Array in JavaScript

I have just figured out some great way to find the min and max value from the array and I just wanted to share with all of you.

See the code below, use it or add console log to understand it in depth.

var arr = [12, 89, 67, 55];

// Method 1

function arrayMax(arr) {

return arr.reduce(function(p, v) {

return Math.max(p, v); // Math.min for min

});

}

arrayMax(arr);

// Method 2

function arrayMax(arr) {

return arr.reduce(function(p, v) {

return p > v ? p : v; // p < v for min

});

}

arrayMax(arr);

// Method 3

Math.max(...arr); // Math.min for min

// Method 4

function findMinMax(arr) {

let min = arr[0],

max = arr[0];

for (let i = 1, len = arr.length; i < len; i++) {

let v = arr[i];

min = v < min ? v : min;

max = v > max ? v : max;

}

return [min, max];

}

findMinMax(arr);
