The Simple Trick to Squaring Numbers in JavaScript!

Squaring a number is a basic mathematical operation that involves multiplying a number by itself. In JavaScript, there are several ways to perform this operation. This article will explore different methods to square a number and provide examples for each approach.

01. Math.pow() Method

The Math.pow() method is a built-in JavaScript function that can be used to raise a number to a specified power. To square a number, you raise it to the power of 2.

// Squaring a number using Math.pow()
const number = 5;
const squared = Math.pow(number, 2);
console.log(squared); 

// Output: 25

• Math.pow(number, 2) raises the number to the power of 2, effectively squaring it.

02. Exponentiation Operator (**)

The exponentiation operator (**) is a more recent addition to JavaScript, providing a concise syntax for exponentiation. To square a number, you use this operator with an exponent of 2.

// Squaring a number using the exponentiation operator
const number = 5;
const squared = number ** 2;
console.log(squared); 

// Output: 25

• number ** 2 squares the number using the exponentiation operator.
