ES6第二部分

1.解构赋值-数组篇 //Destrcturing(解构)
//ES5
/*
var a = 1;
var b = 2;
var c = 3;
*/
//ES6
var [a,b,c] = [1,2,3];
console.log(b);

//demo2
let [
foo,
[
[bar],
base
]
] = [
1,
[
[2],
3
]
];

console.log(bar);//2
console.log(base);//3

//demo3
let [,a,] = [1,2,3];
console.log(a);//2

//demo4
let [zero,...j] = [0,1,2,3,4]; //注意是三个.
console.log(j); //[1,2,3,4]
//demo5
let [a,b] = [1];
console.log(a); //1
console.log(b); //undefined

//demo6 不完全解构
let[a,[b],c] = [1,[2,3],4];
console.log(b); //2
console.log(c);//4

//demo7 制定默认值
var [temp = ‘jewave‘] = [];
console.log(temp);//‘jewave‘

// var [temp=‘jewave‘] = [‘xiang‘];
// var [p,q = ‘aaa‘] = [‘bbb‘,undefined] 【‘bbb‘,‘aaa‘】
// var [temp] = 1; 报错 var [temp]= undefined;报错
