JavaScript Array Clear

Clear() method is used to clear all the defined array. In this section, you will study how to clear the Array in JavaScript. You can see in the given example, we have create an instance of array which consists of elements 'Hello' and 'World'. Then we have used the clear() method which removes all elements from an Array instance. After removing the array by clear() method, the resulting array's length will become zero.

Here is the code:

<html>
<head>
<h2> Array Clear Example</h2>
<script>
var array=new Array();
array[0]="Hello";
array[1]="World";
document.write("<b>Array is: </b> <br> ")
for (var i = 0; i < array.length; i++){
document.write(array[i] + "<BR>");
}
document.write("<b>Now the Array is:</b> <br><br>");
array.clear();
for (var i = 0; i < array.length; i++) {
document.write(array[i]+ "<BR>");
}
</script>
<b>[After using the clear() method, the array is removed.]</b>
</head>
<body bgcolor="lightBlue"/>
