Object.keys() · Return an array of an object's own enumerable property names, in insertion order (integer keys first).
Object.values() · Return an array of an object's own enumerable property values, in the same order as Object.keys().
Object.fromEntries() · Build an object from an iterable of [key, value] pairs, such as an array or a Map. The opposite of Object.entries().
array.entries() · Return an iterator of [index, element] pairs, handy for looping with both the index and the value.
