Proxy Made With Reflect 4 2021 -

const cache = new Map();

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. proxy made with reflect 4 2021

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

const proxy = new Proxy(target, handler); const cache = new Map()

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