How to link JavaScript to HTML

Complacency has no place in today’s world. You have only a few seconds to capture and maintain the interest of your viewers. One of the most significant ways to accomplish this is by creating a visually appealing and responsive website. Web apps and web pages can be interactive with the help of JavaScript. Since most browsers widely support JavaScript, this shouldn’t be an issue. Your browser has specific built-in engines that allow this to run. In this article, we look at linking JavaScript to HTML.

How to link JavaScript to HTML is the main question people want to know. As a beginner web developer, you may find yourself in need of a JavaScript library or framework. Do not be alarmed! This tutorial has two techniques to add JavaScript to your HTML files. In HTML, the script> tag connects a JavaScript file. Embedding JavaScript code in an HTML document is also possible using this tag.

Developers can link both JavaScript and HTML using two methods:

  • You can link to an external file. 
  • You can either use a specific tag or insert it simply into your HTML.

The second method, involving JavaScript in an external file, is the more usual one.

How to add JavaScript to HTML

Scripting is a term used to describe languages that must be supported by another language to be run. A JavaScript application, for example, cannot be run unless HTML or HTML code is used to execute it. You can use JavaScript in various ways on a web page, including alerting, picture galleries, DOM manipulation, data validation, and much more.

A user programming language such as JavaScript, sometimes known as JS, is commonly used during website designing to build dynamic and engaging websites. In this context, the term “script” refers to JavaScript, which runs on the local computer and is not an independent program.

How to include external JavaScript in HTML

The external script works as a script tag. Create a JavaScript file with the extension.js outside of the application. After created, paste it inside the script tag of the HTML file. This external JavaScript file is included using the property. Improve page performance by including more external JavaScript files on the same website.

When applied to an HTML document, JavaScript provides dynamic interactivity. JavaScript allows users to create modern web applications that they may use without reloading the page. The DOM API often uses JavaScript to update HTML and CSS to change a user interface.

To embed JavaScript code in an HTML document, use the HTML tag script>. Depending on when you want JavaScript to load, you can insert the script tag in the head or body of your HTML.

The script> and /script> tags in HTML are where JavaScript code is placed. In an HTML document, you can include as many scripts as you like. Both the body and the head of an HTML page can include scripts and both.
