Standard built-in objects
The term "global objects" (or standard built-in objects) here is not to be confused with the global object. Here, global objects refer to objects in the global scope (but only if ECMAScript 5 strict mode is not used; in that case it returns
undefined). The global object itself can be accessed using the
this (en-US) operator in the global scope. In fact, the global scope consists of the properties of the global object, including inherited properties, if any.
These global properties return a simple value; they have no properties or methods.
These global functions—functions which are called globally rather than on an object—directly return their results to the caller.
These are the fundamental, basic objects upon which all other objects are based. This includes objects that represent general objects, functions, and errors.
Numbers and dates
These are the base objects representing numbers, dates, and mathematical calculations.
These objects represent strings and support manipulating them.
These objects represent collections of data which are ordered by an index value. This includes (typed) arrays and array-like constructs.
These objects represent collections which use keys; these contain elements which are iterable in the order of insertion.
SIMD (en-US) vector data types are objects where data is arranged into lanes.
Control abstraction objects
Additions to the ECMAScript core for language-sensitive functionalities.
