Top - Proxy Made With Reflect 4

A common mistake is manually performing the default operation within a trap, like using target[property] . However, this approach has several pitfalls: it can bypass getters/setters on the prototype chain, lose the correct this binding, and fail to handle Symbol properties properly. For example, if a getter returns data based on the this context, target[prop] will return the value in the context of the target , not the proxy itself, potentially causing runtime errors.

The was created to fill the gap left by JDK’s interface-only proxy. Instead of building a class that implements interfaces, CGLIB creates a new class that is a subclass of the target class. It overrides all non-final methods of the superclass to provide the interception logic, a technique enabled by powerful bytecode generation. A common mistake is manually performing the default

The construct trap intercepts the new operator. Reflect.construct() mimics standard instantiation but allows you to alter or extend object creation workflows dynamically. When to Use ; const proxy = new Proxy(target, handler); The
