First you need to download the jQuery library from https://jquery.com/ then load the jQuery library the following way within your HTML head tags.
Then you can test whether jQuery is working by adding your jQuery code after the jQuery loading script.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
$(function(){
alert("My First jQuery Test");
});
</script>
</head>
<body><!-- Your web page --></body>
</html>
If you want to use your jQuery scripts file separately, you must define the external .js file this way after the jQuery library loading.
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script src="js/YourExternalJQueryScripts.js"></script>
Test in real time
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

How to Link JavaScript to HTML
To link a JavaScript file to an HTML document, use the <script> tag. You can also use this tag to embed JavaScript code within the HTML document. To link to an external JavaScript file, use <script src="myExternalFile.js"></script> where myExternalFile.js is the location of the external file.

You can either load an external js file or write your code inside the script tags. Try:
<body>
<header>
<div class="container">
<h1><a href="/">Title</a></h1>
<span id="tagline"></span>
</div>
</header>
<script src="js/tagline.js"></script>
<script>showTagline();</script>
</body>
Place your script tags at the end of the body. You are using the id to access the span, the placement of the function call does not matter.

You can get the function by loading the js file, and call the function with an onclick event, for example:
<body>
<header>
<div class="container">
<h1><a href="/">Title</a></h1>
<span id="tagline">
<button onclick="showTagline()">Click me</button>
</span>
</div>
</header>
<script src="js/tagline.js"></script>
</body>

r/learnjavascript on Reddit: How to link js file to html file without the need to use full paths ?
April 8, 2023 -
I set up a simple project in Vscode , I made a simple html and js file . First one , I test by put all js file content into script tag in html file , worked fine . The thing is when I create new js file , it stop linked together.
The structure of my project is Projects/project1/project.html and project.js inside the same folder as project.html
I have tried src=“project.js” ,”/project.js”…. Any combination possible but it didnt worked, the only thing that worked is the full path : “file:///Users/admin/Desktop/Projects/project1/project.js “ which I think really long
So what is the right path to link those two file without the need to use full path in this projects ?

- Use this to link your JS file. Make sure that the file path in the src attribute matches the actual file path and name of your JavaScript file. If you're still having trouble, double-check that both your HTML and JavaScript files are in the same directory and that the file names and extensions are correct.

You don't need to use full paths, you need to use relative paths. Is your html file in the same directory as your JavaScript file?
