Prototype - Enumerable zip() Method
This method zips together 2 + sequences, providing an array of tuples.
Each tuple contains one value per original sequence. Tuples can be converted to something else by applying the optional iterator on them.
Syntax
Iterator.zip(Sequence);
Return Value
Returns an array of zipped values.
Example
<html>
<head>

<script type = "text/javascript" src = "/javascript/prototype.js"></script>
<script>
function showResult() {
var firstNames = ['Justin', 'Tobie', 'Christophe'];
var lastNames = ['Palmer', 'Langel', 'Porteneuve'];
var zipped = firstNames.zip(lastNames);
alert("zipped values: " + zipped.inspect());
var zipped = firstNames.zip(lastNames, function(a) {
return a.join(' ');
})
alert("zipped values: " + zipped.inspect());
}
