Description
Reflect.get() provides the reflective semantic of aproperty access. That is,Reflect.get(target, propertyKey, receiver) is semantically equivalent to:
target[propertyKey];Note that in a normal property access,target andreceiver would observably be the same object.
Reflect.get() invokes the[[Get]]object internal method oftarget.

// Objectconst obj1 = { x: 1, y: 2 };Reflect.get(obj1, "x"); // 1// ArrayReflect.get(["zero", "one"], 1); // "one"// Proxy with a get handlerconst obj2 = new Proxy( { p: 1 }, { get(t, k, r) { return `${k}bar`; }, },);Reflect.get(obj2, "foo"); // "foobar"// Proxy with get handler and receiverconst obj3 = new Proxy( { p: 1, foo: 2 }, { get(t, prop, receiver) { return `${receiver[prop]}bar`; }, },);Reflect.get(obj3, "foo", { foo: 3 }); // "3bar"Specifications
