# 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>
    <title>Prototype examples</title>
    <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());
    }

    </script>
    </head>
