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).
