Find Square Root of a Number – JavaScript Program

Find Square Root of a Number Program

In this tutorial, you are given a number. Write a JavaScript program with a function that takes the number as argument, finds the square root of this number, and returns the result.


To find the square root of a number in JavaScript, we can use Math.sqrt() method.


1. In the following program, we take a number in n, find its square root, and print the result to console output.

function findSquareRoot(num) {
    return Math.sqrt(num);

var n = 5;
const result = findSquareRoot(n);

Math.sqrt() function is used in the above program. JavaScript Math library contains trivial functions related to mathematics.
