2 Easy Ways To find the difference between largest and smallest numbers in array Javascript

Today we are going to learn different methods to find the difference between largest and smallest numbers in array javascript.

We already saw how to find smallest number in array and find largest number in array javascript. With the help of these two methods we are going to find difference between largest and smalles numbers in array.

Difference between largest and smallest numbers in array using Math.min() and Math.max()

First we are going to find largest number,

let arr = [10, 20, 30, 40, 50];

Using spread operator we are going to spread out the array as series of elements then pass it to Math.max() function.

let largestNumber = Math.max(...arr);

console.log(largestNumber);

Now we are going to find the smallest number from the array,

Using spread operator we are going to spread out the array as series of elements then pass it to Math.min() function.

let smallestNumber = Math.min(...arr);

console.log(smallestNumber);

It’s time to find the difference between largest and smallest number,

let differnce = largestNumber - smallestNumber;
console.log(difference);

Difference between largest and smallest numbers in array using lodash
