The Key Master

Easy+20 XP

Mission Briefing

The Grand Master requires a complete inventory of all the vault's compartments! You don't need to know what's inside them, you just need a list of the compartment names themselves.

The Concept: Object Keys

The Object.keys(obj) method takes an object and returns an array containing all of the object's property names (keys) as strings. Example: Object.keys({ a: 1, b: 2 }); // Returns ["a", "b"]

The Objective

Your function receives a data object.

Use Object.keys() on the object.
Return the resulting array of strings.

01EXAMPLE 1

Inputdata = { a: 1, b: 2 }

Constraints

Use the Object.keys() method.
