const myFunction = () => {
    console.log("execute this function")
};
const handler = {
    set: function (target, prop, value) {
        if (prop === 'name' && value === 'Jack') {
            // calling another function
            myFunction();
        }
        else {
            console.log('Can only access name property');
        }
    }
};

const proxy = new Proxy({}, handler);

proxy.name = 'Jack'; // execute this function
proxy.age = 33; // Can only access name property
