One of the last major pieces of the ECMAScript standard we are going to touch on is two metaprogramming objects. Metaprogramming is the technique of having code that generates code. This could be for things such as compilers or parsers. It could also be for self-changing code. It can even be for runtime evaluation of another language (interpreting) and doing something with this. While this is probably the main feature that reflection and proxies give us, it also gives us the ability to listen to events on an object.
In the previous chapter, we talked about listening to events and we created a CustomEvent to listen for events on our object. Well, we can change that code and utilize proxies for that behavior. The following ...
