What is security in JavaScript?
JavaScript has its own security model, but this is not designed to protect the Web site owner or the data passed between the browser and the server. The security model is designed to protect the user from malicious Web sites, and as a result, it enforces strict limits on what the page author is allowed to do.
What is the use of Jscrambler?

How do I protect my JavaScript?
One of the ways to protect your code is to obfuscate it to encrypt the code and make it unreadable.
- Protect your code and intellectual property.
- Compact js to also make file size smaller and increase page speed.
- Work with jQuery!, NODE.
- Always to preserve the operational qualities of the code.
Does Webpack obfuscate?
It’s worth mentioning that webpack plugins like Uglify or webpack obfuscator only provide basic minification/obfuscation and can be quickly reversed with automated tools. As so, they fail to properly protect webpack bundle files.
