Used to handle binary data. See the [buffer section][].
-## __dirname
+## \_\_dirname
<!-- type=var -->
Example: running `node example.js` from `/Users/mjr`
- console.log(__dirname);
- // /Users/mjr
+```js
+console.log(__dirname);
+// /Users/mjr
+```
`__dirname` isn't actually a global but rather local to each module.
-## __filename
+## \_\_filename
<!-- type=var -->
Example: running `node example.js` from `/Users/mjr`
- console.log(__filename);
- // /Users/mjr/example.js
+```js
+console.log(__filename);
+// /Users/mjr/example.js
+```
`__filename` isn't actually a global but rather local to each module.
-## clearInterval(t)
+## clearImmediate(immediateObject)
-Stop a timer that was previously created with [`setInterval()`][]. The callback
-will not execute.
+<!--type=global-->
+
+[`clearImmediate`] is described in the [timers][] section.
+
+## clearInterval(intervalObject)
<!--type=global-->
-The timer functions are global variables. See the [timers][] section.
+[`clearInterval`] is described in the [timers][] section.
-## clearTimeout(t)
+## clearTimeout(timeoutObject)
+
+<!--type=global-->
-Stop a timer that was previously created with [`setTimeout()`][]. The callback will
-not execute.
+[`clearTimeout`] is described in the [timers][] section.
## console
Process files with the extension `.sjs` as `.js`:
- require.extensions['.sjs'] = require.extensions['.js'];
+```js
+require.extensions['.sjs'] = require.extensions['.js'];
+```
**Deprecated** In the past, this list has been used to load
non-JavaScript modules into Node.js by compiling them on-demand.
Use the internal `require()` machinery to look up the location of a module,
but rather than loading the module, just return the resolved filename.
-## setInterval(cb, ms)
+## setImmediate(callback[, arg][, ...])
-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.
+<!-- type=global -->
+
+[`setImmediate`] is described in the [timers][] section.
-The interval 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.
+## setInterval(callback, delay[, arg][, ...])
-Returns an opaque value that represents the timer.
+<!-- type=global -->
-## setTimeout(cb, ms)
+[`setInterval`] is described in the [timers][] section.
-Run callback `cb` after *at least* `ms` milliseconds. The actual delay depends
-on external factors like OS timer granularity and system load.
+## setTimeout(callback, delay[, arg][, ...])
-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.
+<!-- type=global -->
-Returns an opaque value that represents the timer.
