Note: This method changes the length of an array!
Syntax
array.shift()

The shift() method is supported in all major browsers.
Tips and Notes
Tip: To remove the last element of an array, use the pop() method.
Example
Example
Remove the first element of an array (this will also change the length of the array):
<script type="text/javascript">
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.write(fruits.shift() + "<br />");
document.write(fruits + "<br />");
document.write(fruits.shift() + "<br />");
document.write(fruits);
</script>
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.write(fruits.shift() + "<br />");
document.write(fruits + "<br />");
document.write(fruits.shift() + "<br />");
document.write(fruits);
</script>
The output of the code above will be:
Banana
Orange,Apple,Mango

Apple,Mango
Orange,Apple,Mango
