Javascript - lowest and highest value in array of numbers

Question

I have an array of numbers. How do I find the highest and the lowest value in that array? What is the simplest solution?

This seems to be the simplest answer to my question:

var arr = [1,2,4]
var min = Math.min(...arr)
var max = Math.max(...arr)

It's based on these answers.

https://stackoverflow.com/questions/1669190/find-the-min-max-element-of-an-array-in-javascript seems to have the right answer to my question. I just don't know how to answer my own question... — BlueSkies, Jul 18 '21 at 20:43

You don't need to. The site already recommends people to check out the other question which was previously asked. — evolutionxbox, Jul 18 '21 at 21:15

How about augmenting the built-in Array object to use Math.max/Math.min instead:

Array.prototype.max = function() {
  return Math.max.apply(null, this);
};

Array.prototype.min = function() {
  return Math.min.apply(null, this);
};

I use this function that display the max and min of an Array

    function arrMinMax(arr){
    const min = arr.reduce((a, b) => Math.min(a, b))
    const max = arr.reduce((a, b) => Math.max(a, b))

    console.log("Array : ["+ arr +"]\nMin : "+min +"\nMax : " +max)
}

this is one method, but is the long way around. Consider removing it from this (since it's a duplicate) and adding it to the duplicate solution page (if it's not already there) – Kinglish Jul 18 '21 at 20:16
