Proxy
Explore how to use JavaScript proxies to intercept and control object behaviors in game development. Understand traps such as get and set for property access and assignment, enabling you to add custom logic and validation to game elements like player data.
We'll cover the following...

Syntax
A proxy is created using the new Proxy constructor with two required arguments: the target and the handler.

A Proxy creates an undetectable barrier around the target object that redirects all operations to the handler object.
