# Global Objects

These objects are available in all modules. The following variables may appear
to be global but are not. They exist only in the scope of modules, see the
[module system documentation][]:

- [`__dirname`][]
- [`__filename`][]
- [`exports`][]
- [`module`][]
- [`require()`][]

The objects listed here are specific to Node.js. There are a number of
[built-in objects][] that are part of the JavaScript language itself, which are
also globally accessible.

## Class: Buffer

* {Function}

Used to handle binary data. See the [buffer section][].

## \_\_dirname

This variable may appear to be global but is not. See [`__dirname`].

## \_\_filename

This variable may appear to be global but is not. See [`__filename`].

## clearImmediate(immediateObject)

[`clearImmediate`] is described in the [timers][] section.

## clearInterval(intervalObject)

[`clearInterval`] is described in the [timers][] section.

## clearTimeout(timeoutObject)

[`clearTimeout`] is described in the [timers][] section.

## console

* {Object}

Used to print to stdout and stderr. See the [`console`][] section.

## exports

This variable may appear to be global but is not. See [`exports`].

## global

* {Object} The global namespace object.

In browsers, the top-level scope is the global scope. This means that
within the browser `var something` will define a new global variable. In
Node.js this is different. The top-level scope is not the global scope;
`var something` inside a Node.js module will be local to that module.

## module

This variable may appear to be global but is not. See [`module`].

## process

* {Object}

The process object. See the [`process` object][] section.

## require()

This variable may appear to be global but is not. See [`require()`].

## setImmediate(callback[, ...args])

[`setImmediate`] is described in the [timers][] section.

## setInterval(callback, delay[, ...args])

[`setInterval`] is described in the [timers][] section.

## setTimeout(callback, delay[, ...args])

[`setTimeout`] is described in the [timers][] section.

## URL

The WHATWG `URL` class. See the [`URL`][] section.

## URLSearchParams

The WHATWG `URLSearchParams` class. See the [`URLSearchParams`][] section.

## WebAssembly

* {Object}

The object that acts as the namespace for all W3C
[WebAssembly][webassembly-org] related functionality. See the
[Mozilla Developer Network][webassembly-mdn] for usage and compatibility.
