将对象转换为多维数组-JavaScript

Question

I have an object like this:

var myObj = {
    a: 1,
    b: 2,
    c: 3,
    d: 4
};

And i want to convert that object to a multi-dimensional array like this:

var myArray = [['a', 1], ['b', 2], ['c', 3], ['d', 4]];

How could i achieve this?

Answer 1

You can use Object.entries function.

 var myObj = { a: 1, b: 2, c: 3, d: 4 }, myArray = Object.entries(myObj); console.log(JSON.stringify(myArray)); 

...or Object.keys and Array#map functions.

 var myObj = { a: 1, b: 2, c: 3, d: 4 }, myArray = Object.keys(myObj).map(v => new Array(v, myObj[v])); console.log(JSON.stringify(myArray)); 

Answer 2

 var myArray = []; var myObj = { a: 1, b: 2, c: 3, d: 4 }; for(var key in myObj) { myArray.push([key, myObj[key]]); } console.log(JSON.stringify(myArray));
