Mathematical calculations represent a significant portion of everyday programming tasks. Amongst those operators, exponents hold special importance, especially when tackling problems involving growth rates, decay factors, or powers.

Although JavaScript initially lacked an explicit exponentiation operator, ES2016 introduced the “ notation, bringing parity with other C-family languages.

This article unravels the mysteries surrounding JavaScript’s exponentiation operator (**), covering its background, proper usage, caveats, comparing it with alternative implementations, and highlighting valuable tips to maximize its impact.

Background

Historically, JavaScript programmers relied on Math.pow() to calculate exponents, occasionally resorting to awkward self-implementations or library imports. Thankfully, ES2016 paved the way for a dedicated exponentiation operator (**), shortening syntax and increasing legibility.

Basic Syntax and Examples

At its core, the exponentiation operator calculates the base raised to the specified power:
