For example, I have the object names:

let names = { name: 'Jhon', lastName: 'Doe' }

Now, what I want to do is to search a key of the names object using a variable. For example I have the variable:

let variable = 'lastName';

What I want to do is to search the object key value like this:

console.log(names.variable)

And it should print Doe. How can I do that?

like you would with an array: `console.log(names[variable]);` – ControlAltDel Jun 27 '19 at 18:30

@ControlAltDel it worked! Can you please comment it as an answer so I can mark it as the solution? – Paul Miranda Jun 27 '19 at 18:35
