In software development, a proxy is an object that acts as an intermediary between a client and a server, allowing for more control over the communication between the two. With the release of Reflect 4 2021, developers can now create proxies with even more ease and flexibility. In this article, we'll explore how to create a proxy using Reflect 4 2021 and discuss its potential use cases. proxy made with reflect 4 2021
const proxy = new Proxy(target, handler); const target = { foo: 'bar' }; In
const target = { expensiveComputation: () => { // simulate an expensive computation return new Promise((resolve) => { setTimeout(() => { resolve(Math.random()); }, 2000); }); } }; const proxy = new Proxy(target, handler); const target
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.
