js includes

JavaScript includes are code snippets or files that can be included in a webpage to add functionality, interactivity, or styling. They can be used to:

1. Add interactivity to web pages: JavaScript can be used to add interactivity to web pages, such as form validation, button clicks, or animations.

2. Manipulate the Document Object Model (DOM): JavaScript can be used to modify the structure, content, and styling of a web page.

3. Handle events: JavaScript can be used to handle events such as mouse clicks, keyboard input, or page loading.

4. Communicate with servers: JavaScript can be used to send and receive data from servers asynchronously, without reloading the page.

There are several ways to include JavaScript in a web page:

1. Inline scripts: JavaScript code can be included directly in the HTML file using the <script> tag.

2. External scripts: JavaScript code can be stored in a separate file and included in the HTML file using the <script> tag with the src attribute.

3. JavaScript libraries: JavaScript libraries are collections of pre-written code that can be included in a web page to add specific functionality, such as jQuery or React.

4. Frameworks: JavaScript frameworks are collections of libraries that provide a structure and set of conventions for building web applications, such as Angular or Vue.
