Methods in Reflect

Reflect is similar to the method in Object. Vue3 uses two-way binding implemented by proxy and reflect. Therefore, let's learn the method in Reflect and deepen your understanding

1 Reflect.get

Usually used with proxy to get attribute value

let x={p:1,foo:2}let y={foo:3}let obj=new Proxy(x,{get(target,key,receiver){console.log(receiver[key]+'bar')}})Reflect.get(obj,'foo',y) //3bar

2 Reflect.set

For setting properties

const target={set a(v){this.b=v}}const reveiver={}Reflect.set(target,'a',3span>,receiver)

3 Reflect.has

Check for an attribute

4 Relfect.ownKeys

Used to traverse the object, you can traverse the properties of the symbol as the key name

5 Reflect.deleteProperty

Delete an attribute
