JavaScript codes for Web DEV

[JavaScriptBank]

During coding JavaScript applications, we usually have to work with many JavaScript arrays; and sometimes declare/initiate them is the time-consuming tasks.

For this reason, I would like to present... detail at JavaScriptBank.com - 2.000+ free JavaScript codes

How to setup

Step 1: Use CSS code below for styling the script
CSS

<style type="text/css">
#display {
  position: relative;
  left: 10px;
  width: 450px;
  border: 1px solid black;
  padding: 10px;
}
</style>

Step 2: Use JavaScript code below to setup the script
JavaScript

<script type="text/javascript">
