The for...in statement is used to loop (iterate) through the elements of an array or through the properties of an object.

For...In Statement

There are two special statements that can be used inside loops: break and continue.

Break

The for...in statement is used to loop (iterate) through the elements of an array or through the properties of an object.

The code in the body of the for ... in loop is executed once for each element/property.

The Code

<html>
<body>
<script type="text/javascript">
var x;
var mycars = new Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";
for (x in mycars)
{
document.write(mycars[x] + "<br />");
}
