快速获取对象所有属性的方法

**

快速获取属性的方法,在日常的 接触中 大概了解了 以下几种 :

**

1.使用 Object.keys方法

	const a = {
        name: "ls",
        age: 18,
        score: 99,
        getProperty: function() {
        return this.age
      }
  	console.log(Object.keys(a))
  	// ["name", "age", "score", "getProperty"]

2.使用 object.hasOwnpropertyName()

const b = {
        name: "ls",
        age: 18,
        score: 99,
        getProperty: function() {
        return this.age
      }
    console.log(Object.hasOwnpropertyName(b))

3.使用 Reflect.ownKeys()

	const C = {
        name: "ls",
        age: 18,
        score: 99,
        getProperty: function() {
        return this.age
      }
    console.log(Reflect.ownKeys(b))

4. for in循环

		const a = {
        name: "ls",
        age: 18,
        score: 99,
        getProperty: function() {
        return this.age
      }
	 const property = [];
      for (const key in a) {
        if (a.hasOwnProperty(key)) {
          property.push(key);
        }
      }
      console.log(property);
      //["name", "age", "score", "getProperty"]
