JavaScript - Proxy Is the Sledgehammer.

proxy is a tool that lets you do like everything and anything. The idea behind proxy was to make it possible to have all these weird, whacky behaviors within the javascript language itself. You can still access if the original object is unmodified. If you work with the original object, it works in the same way. But if you use the proxy object, then you've got total control over how things are access you.
