The Basics of Scripting
Scripting involves writing a series of instructions or commands that are executed by the browser or server. These instructions are written in a scripting language and can be embedded directly within the HTML code of a webpage or stored in separate script files that are linked to the HTML document using the
<script> tag. This tag can be placed anywhere within the
<body> section of the HTML document.
Note: It is generally considered best practice to place script tags at the bottom of the
<body> section to ensure that all HTML content has been loaded before executing any scripts.
<script> tags. This code selects the HTML element with the id “demo” and changes its content to display “Hello, World!”
For larger scripts or when reusing code across multiple web pages, it is often more convenient to store the script in an external file with a
.js extension. To link this file to an HTML document, we use the
<script> tag with the
src attribute pointing to the location of the script file.
In this example, we have linked an external script file called "script.js" using the
<script src="">tag. The contents of this script file could be similar to our previous example.
The Power of Scripting
- Data Validation: Scripting enables us to validate user input in real-time and provide feedback based on specific validation rules.
- Data Storage: Scripting languages allow us to store data locally in the browser using mechanisms like cookies or web storage.
The possibilities with scripting are virtually endless. By combining HTML markup and CSS styling with scripting languages, we can create dynamic and interactive web applications that engage users and provide a rich browsing experience.

Becoming proficient in scripting opens up numerous opportunities for creating dynamic websites that stand out from static pages. So go ahead, experiment with scripting languages, and unlock the true potential of web development!
