Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

TheMath.cbrt() static method returns the cube root of a number. That is

𝙼𝚊𝚝𝚑.𝚌𝚋𝚛𝚝 (𝚡) = \sqrt[3]{x} = the unique y such that y^{3} = x \mathtt{\operatorname{Math.cbrt}(x)} = \sqrt[3]{x} = \text{the unique } y \text{ such that } y^3 = x

Try it

console.log(Math.cbrt(-1));// Expected output: -1console.log(Math.cbrt(1));// Expected output: 1console.log(Math.cbrt(Infinity));// Expected output: Infinityconsole.log(Math.cbrt(64));// Expected output: 4

Syntax

Math.cbrt(x)

Parameters

x: A number.

Return value

The cube root ofx.

Description

Becausecbrt() is a static method ofMath, you always use it asMath.cbrt(), rather than as a method of aMath object you created (Math is not a constructor).
