+Creates an array of key-value pair arrays from an object.
+
+Use `Object.keys()` and `Array.prototype.map()` to iterate over the object's keys and produce an array with key-value pairs.
+
+```js
+const objectToEntries = obj => Object.keys(obj).map(k => [k, obj[k]]);
+```
+
+```js
+objectToEntries({ a: 1, b: 2 }); // [ ['a', 1], ['b', 2] ]
+```
