JS: Object.entries

(new in ECMAScript 2017)

Object.entries(obj)

• Convert object to Array.
• Each property is converted to array [key, value].
• Only consider properties that are own, string key, and Enumerable. Others are ignored.
• Return the new array.

console.log(Object.entries({ a: 3, b: 4 }));
// [ [ "a", 3 ], [ "b", 4 ] ]
