## Introduction

The exponentiation operator is an arithmetic operator introduced in ES2016.

A double asterisk is used to calculate the exponent value of a number.

It is equivalent to the traditional pow() function of the Math library.

## Demo

let a = 2;
let b = 3; /*from w w w . ja v a 2 s . c om*/
a ** b //8
**Math**.pow(a, b) // 8

Using the exponentiation Operator is a quick way to calculate the value when a number is raised to the corresponding power.
