Get the highest value of an Array in JavaScript

Get the highest value of an Array

To get the highest value of an array, we can use the Math.max() method by passing the array of elements as a argument to it. So, it returns the highest value from the given array.

Here is an example:

const arr = [2, 4, 55, 34, 12];

const highestValue = Math.max(...arr);
console.log(highestValue);

Output:

55

In the example above, we have used the Math.max(..arr) to get the highest value of an array in JavaScript.

The Math.max() method only accepts the individual values as an arguments but not an array, so we unpacked the array by using the es6 (…) spread operator and passed to it.

We can also call Math.max() method without unpacking the array by using the Function.prototype.appl() method.

Here is an example:

const arr = [2, 4, 55, 34, 12];

const highestValue = Math.max.apply(null, arr);
console.log(highestValue);
