Can You Truly Hide JavaScript Code from View Source?

Can JavaScript Code Be Concealed from Webpage View Source?

It is impossible to entirely hide JavaScript code from view source when a browser's "View Source" feature is used. If the browser can execute the code, any viewer can access and execute it as well.

However, it is possible to relocate JavaScript code to an external .js file and reference it through script tags:

<code class="html"><script type="text/javascript" src="http://mydomain.example/xxxx.js"></script></code>

This approach prevents the JavaScript code from being directly visible in the view source. However, users can still retrieve the external .js file to access the code.

To further enhance protection, consider implementing the following measures:

1. Obfuscate the code to obscure variable names and remove unnecessary whitespace.
2. Dynamically include the .js file through programmatic script tag manipulation.
3. Host crucial application logic on the server and retrieve it through AJAX calls, minimizing the amount of code exposed locally.

While these steps can complicate code retrieval, focusing on exceptional performance, reliability, and user experience should take precedence over hiding proprietary algorithms. Server-side implementation should be reserved for genuinely sensitive data or complex algorithms.
