Ok, let's say you have a string: "(hello) (world) (something) (number 4)"
And in javascript, you wanted to get the contents between the brackets in chronological order. You can use indexOf() but how can you deal with multiple possibility.

using match and map may be an idea:
"(hello) (world) (something) (number 4)"
.match(/\(.+?\)/g)
.map(function(a){return a.replace(/[\(\)]/g,'');})
//=> ["hello", "world", "something", "number 4"]
See MDN on the Array.prototype.map method, also offers a shim for older browsers

did the `map` method replace all `()` with nothing? and how did you put it in an array? – Pixeladed Aug 17 '13 at 12:13

The `match` methods' result is an array containing all parenthesized words of the string (as per the regular expression `/\(.+?\)/g`). The `map` method replaces the parentheses of every element of that array with an empty string. – KooiInc Aug 17 '13 at 13:13
