In the ever-evolving world of JavaScript, developers are constantly seeking new ways to enhance their code and improve its functionality. One powerful tool that has gained significant attention in recent years is the Proxy object.

Proxy objects provide a unique way to intercept and modify the fundamental operations performed on objects, allowing you to create custom behavior and add additional layers of control to your applications.

Understanding Proxy Objects

At its core, a Proxy object is a wrapper around another object, known as the “target” object. The Proxy object intercepts and can optionally modify the fundamental operations performed on the target object, such as property access, assignment, and function calls.

This interception mechanism gives developers the ability to customize the behavior of objects in ways that were previously not possible. The Proxy object is defined using the new Proxy() constructor, which takes two arguments: the target object and a handler object.
