You can get an array of object keys. Let's see how it's done. Let's have the following object:

javascriptlet obj = {a: 1, b: 2, c: 3};

Get an array of its keys:

javascriptlet keys = Object.keys(obj);

Let's output this array to the console:

javascriptconsole.log(keys);

javascriptlet obj = {x: 1, y: 2, z: 3};
