Javascript Array - slice method


The slice method copies a continuous block of array and retuns it to new array. It can have either no argument, 1 argment or 2 arguments/
- If you specify one no argument, it will return the complete array.

- If you specify one integer argument, it specifies the start of the index from which we need to copy.

- If you specify two arguments, then it tells the begining and end of the index to copy. Take a look at the following example 

<html>
<body>

<script type="text/javascript">


var a = [1,2,3,4,5,6,7,8,9,10];

var x = a.slice();
document.writeln(x+'<BR>');        // outputs: 1,2,3,4,5,6,7,8,9,10

var y = a.slice(4);
document.writeln(y+'<BR>');        // outputs: 5,6,7,8,9,10

var z = a.slice(4,7);
document.writeln(z+'<BR>');        // outputs: 5,6,7
</script>

</body>
</html>
