When browsing the internet, you may come across websites with interactive features and dynamic content powered by JavaScript. JavaScript is a popular programming language that adds functionality and interactivity to web pages. If you’re curious about how a website is utilizing JavaScript or want to learn from the code, you may wonder how to see the JavaScript of a website. In this article, we will explore different methods to accomplish this task.

Using the Browser Developer Tools

Modern web browsers come equipped with developer tools that allow you to inspect and analyze the elements of a web page, including its JavaScript code. Here’s how you can access the JavaScript of a website using the developer tools:

Step 1: Open the website you want to inspect in your preferred web browser.

Step 2: Right-click on any part of the webpage and select “Inspect” or “Inspect Element” from the context menu. This will open the browser’s developer tools panel.

Step 3: In the developer tools panel, navigate to the “Sources” or “Debugger” tab. This tab usually contains the JavaScript code of the website.

Step 4: Explore the JavaScript files and their contents. You can view and modify the code, set breakpoints for debugging, and even run specific code snippets.

Using the browser’s developer tools, you can gain insights into how a website is utilizing JavaScript and understand its functionality.

Viewing External JavaScript Files

Many websites load JavaScript code from external files rather than embedding it directly into the HTML. To view these external JavaScript files, follow these steps:

Step 1: Open the website you want to inspect in your browser.

Step 2: Right-click on the webpage and select “View Page Source” or “Inspect Element” to open the developer tools.

Step 3: In the developer tools panel, navigate to the “Network” or “Sources” tab.

Step 4: Reload the webpage by pressing the F5 key or clicking the refresh button.

Step 5: Look for JavaScript files in the list of network requests or sources. These files are often indicated by a “.js” extension.

By examining the external JavaScript files, you can gain a deeper understanding of how a website is structured and how different components interact with each other.

Using Online Tools

If you prefer not to use the browser’s developer tools, there are online tools available that can help you see the JavaScript code of a website. These tools allow you to enter the URL of a website and retrieve its JavaScript code for analysis. Here are a few popular online tools:

JS Beautifier: This tool reformats minified or obfuscated JavaScript code, making it more readable and understandable.
JSDetox: JSDetox is a tool specifically designed to deobfuscate JavaScript code, helping you uncover its true functionality.
Wappalyzer: Wappalyzer is a browser extension that not only identifies the technologies used on a website but also provides access to the JavaScript code.

Using online tools can be convenient if you want a quick and easy way to view the JavaScript code of a website without diving into the technicalities of browser developer tools.


Being able to see the JavaScript code of a website can be a valuable learning experience and provide insights into how different websites implement functionality and interactivity. By using the browser’s developer tools or online tools, you can explore the JavaScript code and gain a deeper understanding of how it contributes to a website’s overall functionality.
