JS将对象转化为数组

1
let obj={a:1,b:2}
2
let arr = []
3
let x=Object.entries(obj)//[["a", 1],["b", 2]]
4
arr=x.map(item=>{
5
    return item[1]
6
})
7
console.log(arr)//[1,2]

1
let obj={a:1,b:2}
2
let arr = []
3
for (let i in obj) {
4
    arr.push(obj[i]); //属性
5
    //arr.push(obj[i]); //值
6
}
7
console.log(arr);//[1,2]

1
let obj={a:1,b:2}
2
let arr = Object.values(obj)
3
console.log(arr);//[1,2]
