# Javascript Math Objects - Properties and Methods

## Description

JavaScript **math object** is a top-level, a predefined object for mathematical constants and functions.

Can not be created by the user. It is a predefined object

Mathematical properties and functions can be calculated by **math.property** or **math.method** (for example math.abs(4.568)).
