# Global Objects#

These objects are available in all modules. Some of these objects aren't actually in the global scope but in the module scope - this will be noted.

## global#

- {Object} The global namespace object.

In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope `var something` will define a global variable. In Node this is different. The top-level scope is not the global scope; `var something` inside a Node module will be local to that module.

## process#

- {Object}

The process object. See the process object section.

## console#

- {Object}

Used to print to stdout and stderr. See the stdio section.

## Buffer#

- {Object}

Used to handle binary data. See the buffer section.

## require()#

- {Function}

To require modules. See the Modules section. `require` isn't actually a global but rather local to each module.

### require.resolve()#

Use the internal `require()` machinery to look up the location of a module, but rather than loading the module, just return the resolved filename.

### require.cache#

- Object

Modules are cached in this object when they are required. By deleting a key value from this object, the next `require` will reload the module.

## __filename#

- {String}

The filename of the code being executed. This is the resolved absolute path of this code file. For a main program this is not necessarily the same filename used in the command line. The value inside a module is the path to that module file.

Example: running `node example.js` from `/Users/mjr`

    console.log(__filename);
    // /Users/mjr/example.js

`__filename` isn't actually a global but rather local to each module.

## __dirname#

- {String}

The name of the directory that the currently executing script resides in.

Example: running `node example.js` from `/Users/mjr`

    console.log(__dirname);
    // /Users/mjr

`__dirname` isn't actually a global but rather local to each module.

## module#

- {Object}

A reference to the current module. In particular `module.exports` is the same as the `exports` object. See `src/node.js` for more information. `module` isn't actually a global but rather local to each module.

## exports#

An object which is shared between all instances of the current module and made accessible through `require()`. `exports` is the same as the `module.exports` object. See `src/node.js` for more information. `exports` isn't actually a global but rather local to each module.

See the module system documentation for more information.

See the module section for more information.

## setTimeout(cb, ms)#

## clearTimeout(t)#

## setInterval(cb, ms)#

## clearInterval(t)#

The timer functions are global variables. See the timers section.
