Is JavaScript case-sensitive?

Answer»

The array VARIABLE is to be set empty if you want to empty an array.

Let’s SAY we have the following array:

var myArr = ["shirt", "trousers", "WATCH"];

To empty the above array, just set it to empty:

myArr = [];

Here we converting our array to empty array:

<html>    <head>       <title>Empty Array in JAVASCRIPT</title>       <script>          var myArr = ["shirt", "trousers", "watch"];          document.write("<BR />Array: " + myArr );          // set array to empty          myArr = [];          document.write("<br />New array (Empty now): " + myArr );       </script>    </head>    <body>    </body> </html>

The output:

Array: shirt,trousers,watch New array (Empty now):
