1.对象编写的规范

//创建对象const item = {}//为对象创建动态属性const obj = {  id:5,  name:'San Francisco',  [getKey('enabled')]:true}//在对象中写method规范const atom = {  value:1,  addValue(value){    return atom.value + value;  }} //对象中写属性简写const store = 'value'const obj = {  store}//在开头分组属性简写const store = 'value'const moblie = '189****8544'const obj = {  store,  mobile,  address:'xxx xxx',  nickName:'xxx'}//只对无效的key值加引号，使其生效const obj = {  foo:3,  bar:4,  'data-name':'xiaokyo'}//利用拷贝获得新的对象const original = { a:1,b:2 }const copy = {...original,c:3} // copy => {a:1,b:2,c:3}const {a,...noA} = copy // noA => {b:2,c:3}
