Find the min/max element of an Array in JavaScript

Question

How can I easily obtain the min or max element of a JavaScript Array?

Example Psuedocode:

let array = [100, 0, 50]

array.min() //=> 0
array.max()         


        

Answer 1

I thought I'd share my simple and easy to understand solution.

For the min:

var arr = [3, 4, 12, 1, 0, 5];
var min = arr[0];
for (var k = 1; k < arr.length; k++) {
  if (arr[k] < min) {
    min = arr[k];
  }
}
console.log("Min is: " + min);

And for the max:

var arr = [3, 4, 12, 1, 0, 5];
var max = arr[0];
for (var k = 1; k < arr.length; k++) {
  if (arr[k] > max) {
    max = arr[k];
  }
}
console.log("Max is: " + max);
