JavaScript is a scripting language that can add dynamic content to websites. In modern websites, JavaScript plays an important role, allowing users to interact with the website and create dynamic effects. If you want to implement JavaScript functions on your website, you need to create a JavaScript package.

The following are the steps required to build a JavaScript package:

Step 1: Create a folder
First, we need to create a folder on the computer to store the files containing JavaScript code . It is recommended to give the folder a clear name so that other developers can easily find and access it.

Step 2: Create HTML file
Create an HTML file and name it index.html. This HTML file will be our entry point for referencing the JavaScript file. In this file, add the following code:

<!doctype html>
<html>
<head>
    <title>My JavaScript Package</title>
</head>
<body>
 
    <script src="myscript.js"></script>
</body>
</html>

Copy after login

This code snippet contains a JavaScript file, myscript.js. The src attribute value myscript.js here should match the name of the JavaScript file created in the third step.

Step 3: Create JavaScript file
Create a new JavaScript file and name it myscript.js. In this file, start writing JavaScript code. Meanwhile, in the local file system, this file should be stored in the same folder as index.html to be referenced in the HTML file.

Step 4: Add function code
In order to implement JavaScript functions in the website, JavaScript code needs to be added to the myscript.js file. For example, here is a simple JavaScript example that pops up an alert box when the page loads:

window.onload = function() {
    alert("Hello, world!");
};

Copy after login

Step 5: Save the file
After adding the JavaScript code, save the myscript.js file. It's best to keep the file in the same folder as the index.html file to ensure they can reference each other.

Step 6: Test the website
After completing the above steps, open the index.html file to see if the JavaScript is running normally. If the warning box pops up, it means that the JavaScript code has been successfully run. If it doesn't pop up, you need to check the code for syntax errors or other problems.

The above are the steps required to create a JavaScript package. Through this process, JavaScript code can be implemented on the website. In fact, building a JavaScript package can involve many more steps and complex logic. Again, it is recommended to use a clear naming convention for folder names and files to keep things clean and well-organized during development.
