Explore how to leverage JavaScript's Proxy class for metaprogramming tasks. Understand creating proxies to intercept method calls and dynamically synthesize or alter class behavior based on runtime context.

In an earlier example, in the Injecting Multiple Properties lesson, we introduced a few missing properties like first and last into arrays. This is member injection; we knew what to introduce or inject at code writing time. While that’s fun and useful, member synthesis ups the challenge and the resulting benefits by a few notches:
- With synthesis, we can bring onboard new members into a class based on runtime context.
- We can also alter the behavior of existing methods or
