title: objectToEntries tags: object,array,beginner

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.

const objectToEntries = (obj) => Object.keys(obj).map((k) => [k, obj[k]]);

objectToEntries({ a: 1, b: 2 }); // [ ['a', 1], ['b', 2] ]
