var str = "The quick brown fox jumped over the box like an ox with a sox in its mouth";

str.match(/\w(ox)/g); // ["fox", "box", "sox"]

// match (when used with a 'g' flag) returns an Array with all matches found
// if you don't use the 'g' flag then it acts the same as the 'exec' method.

str.match(/\w(ox)/); // ["fox", "ox"]
/\w(ox)/.exec(str);  // ["fox", "ox"]

There are four kinds of deferral mechanisms in Node.js:

• setTimeout
• setInterval
• setImmediate
• process.nextTick

setTimeout and setInterval are quite familiar to those used to JavaScript in the browser and their semantics are fairly well understood. They return opaque values that can be passed to their clear counterparts, and have been around forever. setImmediate is a newer construct and its adoption in the browser is not very wide, and nextTick is a creation solely unto Node.js. The latter two are mechanisms to queue a callback in the short future, such that currently executing JavaScript may continue. If you're used to trying to do this pattern in the browser you may be used to using something like setTimeout(fn, 0).

If Node.js actually exposed the idea of a turn of the event loop, you would be expecting the scheduled callback to run at the end of the current loop, or the start of the next -- though from the perspective of your application there isn't really a difference. In

To create anchor links that jump down to different sections of a README (as in an interactive table of contents), first create a heading:
#Real Cool Heading

The anchor link for that heading is the lowercase heading name with dashes where there are spaces. You can always get the anchor name by visiting the README on Github.com and clicking on the anchor that appears when you hover to the left of the heading. Copy everything starting at the #:
#real-cool-heading

Wherever you want to link to your Real Cool Heading section, put your desired text in brackets, followed by the anchor link in parentheses:
[Go to Real Cool Heading section](#real-cool-heading)
