Registering JavaScript

JavaScript is a scripting language that allows web developers to create dynamic and interactive web content. In order to use JavaScript on a web page, it must first be registered with the web browser. This is done by including a <script> tag in the HTML of the page.

<script language="javascript">
  // JavaScript code goes here
</script>

The <script> tag is used to define an area of HTML code that will be interpreted by the web browser as JavaScript. The language attribute is used to specify the scripting language being used. In this case, the language is set to "javascript".

The JavaScript code can then be written between the opening and closing script tags. For example, the following code will display an alert box when the page is loaded:

<script language="javascript">
  alert("Hello World!");
</script>

Once the JavaScript code has been written, it needs to be registered with the web browser for it to be executed. This is done by including the <script> tag in the HTML of the page. The web browser will then execute the JavaScript code when the page is loaded.

JavaScript can also be included in external files. This is done by using the src attribute of the <script> tag. This attribute is used to specify the location of the external JavaScript file. For example:

<script language="javascript" src="scripts/myfile.js"></script>

The above code will include the external JavaScript file located at "scripts/myfile.js". The JavaScript code in the external file will then be executed when the page is loaded.

In order to use JavaScript on a web page, it must first be registered with the web browser. This can be done by including a <script> tag in the HTML of the page, or by including an external JavaScript file using the src attribute of the <script> tag.
