Closure Compiler vs DomainLockJS

Closure Compiler is a JavaScript optimizing compiler developed by Google. It analyzes and transforms JavaScript code to make it load faster, run faster, and make it smaller. It removes unused and dead code, checks syntax, rewrites and optimizes code.

DomainLockJS is an open-source JavaScript library that allows websites to prevent other sites from framing their content in iframes. It helps prevent clickjacking attacks by locking the domain to the current page.
