2021: Proxy Made With Reflect 4

Here's an example of how you might use a proxy to implement a simple cache:

console.log(proxy.expensiveComputation()); // takes 2 seconds console.log(proxy.expensiveComputation()); // returns cached result immediately In this example, we create a proxy that caches the results of an expensive computation. The first time the expensiveComputation method is called, the proxy computes the result and caches it. Subsequent calls return the cached result immediately. proxy made with reflect 4 2021

const proxy = new Proxy(target, handler); Here's an example of how you might use

Reflect 4 2021 makes it easy to create proxies that can intercept and modify the behavior of objects. With its powerful features and flexible API, developers can use proxies to build more robust, scalable, and secure applications. Whether you're looking to add logging, security, caching, or virtualization to your app, proxies are definitely worth exploring. const proxy = new Proxy(target, handler); Reflect 4

const target = { expensiveComputation: () => { // simulate an expensive computation return new Promise((resolve) => { setTimeout(() => { resolve(Math.random()); }, 2000); }); } };

Creating a proxy with Reflect 4 2021 is straightforward. Here's an example:
