Script Preparation code:

var baseObject = {
	exampleProp: "exampleValue"
}

var baseMap = new Map();
baseMap.set("exampleProp", "exampleValue");

var baseProxy = new Proxy({}, {
	get(t, prop) {
    	return prop === "exampleProp"? "exampleValue" : null;
    }
})

var baseProxyWithMap = new Proxy({}, {
	get(t, prop) {
    	return baseMap.get(prop);
    }
});

var buffer = null;

Tests:

Proxy with Map
buffer = baseProxyWithMap.exampleProp
Proxy
buffer = baseProxy.exampleProp
