遍历一个对象

Question

let obj = {a:1,b:2,c:3}
let arr = []

-----------
希望结果:
arr = [
{a:1},
{b:2},
{c:3}
]

Answer 1

遍历出结果就for...in就可以

let result = []
for(let k in obj){
    result.push({[k]: obj[k]})
}

如果你想让结果有一定的顺序，那你需要排下序，因为obj是无序的。比如按照ASCII码进行排序

let result = Object.keys(obj).sort().map(k => ({[k]: obj[k]}))

Answer 2

for (key in obj){
   let tmp={};
   tmp[key]=obj[key];
   arr.push(tmp);
}
