es6解构方法(es6解构符号)

导语：ES6解构-实例

1、复杂多级的对象解构

let obj = {    match: {      params: {        id: ,        tab:       }    }  }// 获取id和tabconst { match: {params: {tab,id}}} = obj;console.log(tab);  //‘index’console.log(id);  //‘1’// 获取paramsconst { match: {params}} = obj;console.log(params); //{id: , tab: }// 获取matchconst { match} = obj;console.log(match) ; // {params: {…}}

2、对象数组解构

  let obj = {    isTrue: false,    list: [&39;, &39;]  }  const {list: [list1, list2]} = obj  // list1 &39;   // list1 &39;    let arr = [1,2,3,4,5];const [arr1,arr2,...reset] = arr;// arr1 -> 1// arr2 -> 2// reset => [3,4,5]let arr = [1,2,3,4,5];var [,,,value] = arr;// value => 4
