get: Intercepts property access on the proxy.
set: Intercepts property assignment on the proxy.
apply: Intercepts function invocation on the proxy.
construct: Intercepts class instantiation on the proxy.
has: Checks if the property exists on the proxy.
deleteProperty: Intercepts property deletion on the proxy.
getOwnPropertyDescriptor: Intercepts the retrieval of property descriptors on the proxy.
defineProperty: Intercepts property definition on the proxy.
ownKeys: Returns an array of the proxy object’s own property keys.
getPrototypeOf: Intercepts the retrieval of the prototype of the proxy.
Transparent Interception: Proxies allow developers to intercept operations without modifying the original object, making the interception transparent and non-intrusive.
Dynamic Behaviors: Proxies enable dynamic modifications to the behavior of an object during runtime. This flexibility is especially useful when dealing with complex applications.
Security Enhancements: With proxies, developers can implement security mechanisms by restricting or granting access to certain properties or methods based on user roles or other conditions.
Caching and Optimization: By intercepting property access, proxies can implement caching mechanisms, reducing redundant computations and improving application performance.
Performance Overhead: Proxies involve additional layers of indirection, which may impact performance, especially in critical code paths. Careful consideration is necessary when using proxies in performance-sensitive applications.
