Global Objects

Global Objects

This chapter documents the most useful JavaScript built-in objects, including their methods and properties.

Standard objects by category

Value properties

These global properties return a simple value; they have no properties or methods.

Function properties

These global functions—functions which are called globally rather than on an object—directly return their results to the caller.

Numbers and dates

These are the base objects representing numbers, dates, and mathematical calculations.

Text processing

These objects represent strings and support manipulating them.
