Introduction:
Web development is the process of creating and maintaining websites. It includes everything from conception and planning to coding and design, and can be done either by hand or using specialized software. There are many different aspects to web development, and it can be divided into two main categories: front-end and back-end development.
Front-end development refers to the process of creating the user interface and making it look and function the way we want it to. This includes everything from the layout and design of the website to the actual coding that makes it work.
Back-end development, on the other hand, is all about the server-side of things. It encompasses everything from setting up and configuring the server to actually coding the functionality of the website.
Both front-end and back-end development are important in the overall process of creating a website, and both require a different set of skills.
In this article, we’ll be focusing on front-end development and specifically on the use of separate external JavaScript files.

What are the benefits of using separate external JavaScript files in web development?
There are a few benefits to using separate external JavaScript files in web development:
Organization: When you have a lot of code, it can be difficult to keep everything organized. By putting your code into separate files, you can better keep track of what’s going on.
Reusability: If you have code that you want to use on multiple pages, it’s much easier to just put it in a separate file and include that file on each page that needs it. This way, you don’t have to keep copying and pasting the same code over and over again.
Readability: When your code is organized into separate files, it’s much easier to read and understand. This is especially important if you have other people working on the same project, as they will be able to more easily find and understand the code they need.
How do you go about creating separate external JavaScript files?
Creating separate external JavaScript files is actually quite simple. All you need to do is create a new file with the .js extension and then include that file in your HTML code.
For example, let’s say you have a file called main.js that contains the following code:
function sayHello() {
alert("Hello!");
}
To include this file in your HTML code, you would simply add the following line:
<script src="/main.js"></script>
This line tells the browser to load the main.js file and execute the code within it. You can also include multiple JavaScript files in your HTML code by just adding multiple script tags.
