对象到数组-JavaScript
假设我们有一个像这样的键值对的对象-
const obj = {
name: "Vikas",
age: 45,
occupation: "Frontend Developer",
address: "Tilak Nagar, New Delhi",
experience: 23,
salary: "98000"
};我们需要编写一个函数，该函数接受对象并返回一个数组数组，每个子数组代表一个键值对
示例
让我们为该函数编写代码-
const obj = {
name: "Vikas",
age: 45,
occupation: "Frontend Developer",
address: "Tilak Nagar, New Delhi",
experience: 23,
salary: "98000"
};
const objectToArray = obj => {
const keys = Object.keys(obj);
const res = [];
for(let i = 0; i < keys.length; i++){
res.push([keys[i], obj[keys[i]]]);
};
return res;
};
console.log(objectToArray(obj));输出结果
控制台中的输出：-
[ [ 'name', 'Vikas' ], [ 'age', 45 ], [ 'occupation', 'Frontend Developer' ], [ 'address', 'Tilak Nagar, New Delhi' ], [ 'experience', 23 ], [ 'salary', '98000' ] ]
