It is possible to use Object.entries method:

Object.entries(obj).map(([k, v])=> ({key: k, value: v}));

An example:

let obj = {a: 1, b:2, c:3};
const result = Object.entries(obj).map(([k, v])=> ({key: k, value: v}));
console.log(result);

As mdn says:

The Object.entries() method returns an array of a given object's own enumerable string-keyed property [key, value] pairs, in the same order as that provided by a for...in loop.
