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
-
-<!-- type=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
+## Class: Buffer
<!-- type=global -->
-* {Object}
-
-The process object. See the [process object][] section.
+* {Function}
-## console
+Used to handle binary data. See the [buffer section][].
-<!-- type=global -->
+## \_\_dirname
-* {Object}
+<!-- type=var -->
-Used to print to stdout and stderr. See the [console][] section.
+* {String}
-## Class: Buffer
+The name of the directory that the currently executing script resides in.
-<!-- type=global -->
+Example: running `node example.js` from `/Users/mjr`
-* {Function}
+```js
+console.log(__dirname);
+// /Users/mjr
+```
-Used to handle binary data. See the [buffer section][]
+`__dirname` isn't actually a global but rather local to each module.
-## require()
+## \_\_filename
<!-- type=var -->
-* {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
+* {String}
-* {Object}
+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.
-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.
+Example: running `node example.js` from `/Users/mjr`
-### require.extensions
+```js
+console.log(__filename);
+// /Users/mjr/example.js
+```
- Stability: 0 - Deprecated
+`__filename` isn't actually a global but rather local to each module.
-* {Object}
+## clearImmediate(immediateObject)
-Instruct `require` on how to handle certain file extensions.
+<!--type=global-->
-Process files with the extension `.sjs` as `.js`:
+[`clearImmediate`] is described in the [timers][] section.
- require.extensions['.sjs'] = require.extensions['.js'];
+## clearInterval(intervalObject)
-**Deprecated** In the past, this list has been used to load
-non-JavaScript modules into Node by compiling them on-demand.
-However, in practice, there are much better ways to do this, such as
-loading modules via some other Node program, or compiling them to
-JavaScript ahead of time.
+<!--type=global-->
-Since the Module system is locked, this feature will probably never go
-away. However, it may have subtle bugs and complexities that are best
-left untouched.
+[`clearInterval`] is described in the [timers][] section.
-## __filename
+## clearTimeout(timeoutObject)
-<!-- type=var -->
+<!--type=global-->
-* {String}
+[`clearTimeout`] is described in the [timers][] section.
-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.
+## console
-Example: running `node example.js` from `/Users/mjr`
+<!-- type=global -->
- console.log(__filename);
- // /Users/mjr/example.js
+* {Object}
-`__filename` isn't actually a global but rather local to each module.
+Used to print to stdout and stderr. See the [`console`][] section.
-## __dirname
+## exports
<!-- type=var -->
-* {String}
+A reference to the `module.exports` that is shorter to type.
+See [module system documentation][] for details on when to use `exports` and
+when to use `module.exports`.
-The name of the directory that the currently executing script resides in.
+`exports` isn't actually a global but rather local to each module.
-Example: running `node example.js` from `/Users/mjr`
+See the [module system documentation][] for more information.
- console.log(__dirname);
- // /Users/mjr

-See the [module section][] for more information.
+* {Object}
-## setTimeout(cb, ms)
+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.
-Run callback `cb` after *at least* `ms` milliseconds. The actual delay depends
-on external factors like OS timer granularity and system load.
+### require.extensions
-The timeout must be in the range of 1-2,147,483,647 inclusive. If the value is
-outside that range, it's changed to 1 millisecond. Broadly speaking, a timer
-cannot span more than 24.8 days.
+ Stability: 0 - Deprecated
-Returns an opaque value that represents the timer.
+* {Object}
-## clearTimeout(t)
+Instruct `require` on how to handle certain file extensions.
-Stop a timer that was previously created with `setTimeout()`. The callback will
-not execute.
+Process files with the extension `.sjs` as `.js`:
-## setInterval(cb, ms)
+```js
+require.extensions['.sjs'] = require.extensions['.js'];
+```
-Run callback `cb` repeatedly every `ms` milliseconds. Note that the actual
-interval may vary, depending on external factors like OS timer granularity and
-system load. It's never less than `ms` but it may be longer.
