const obj = {a : 1,b: 1,c: { e : 1}}var proxy = new Proxy(obj,{get(target,property, receiver) {return Reflect.get(target, property, receiver);},set(obj, prop, value) {return obj[prop] = value;},defineProperty(target, property: string, descriptor) {return Reflect.defineProperty(target, property, descriptor);},})export function proxyTest(){proxy.a = 2;}当去掉set方法时,会执行defineProperty;但是当有set方法时,不会执行definePropery;这是为什么呢?
