If you've written software, you've probably written a function, and in so doing you've made up a command. Your program can call that function whenever it needs to.

In many ways, this is the same thing. It's just that the function (or object, method, property, etc.) is defined at a lower level. Sort of at a layer between the parent application and the child script.

It's not that implementors are altering JS itself. It's that they're giving scripts an interface to resources outside of the JS core so that they can do something with them. Which is the entire point of embedding a scripting engine into your software.

I hope that clarifies it a bit.
