Proxy Made With Reflect 4 2021 <Authentic ✦>
const proxy = new Proxy(target, handler);
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.
Creating a proxy with Reflect 4 2021 is straightforward. Here's an example: proxy made with reflect 4 2021
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. const proxy = new Proxy(target, handler); Reflect 4
const handler = { get: (target, prop) => { console.log(`Getting property ${prop}`); return Reflect.get(target, prop); }, set: (target, prop, value) => { console.log(`Setting property ${prop} to ${value}`); return Reflect.set(target, prop, value); } };
const proxy = new Proxy(target, handler); Creating a proxy with Reflect 4 2021 is straightforward
console.log(proxy.foo); // Output: Getting property foo, then "bar" proxy.foo = 'baz'; // Output: Setting property foo to baz console.log(proxy.foo); // Output: "baz" In this example, we create a target object with a single property foo . We then define a handler object that intercepts get and set operations on the target object. Finally, we create a proxy instance, passing in the target and handler objects.
