17,101 PointsCan someone please explain the Person constructor? Including the Object.keys(this). This is really confusing.
I am feel I have a decent grasp on the for in loop but I don't understand the this.getKeys
specifically what is being returned by the Object.keys(this)
.
Other than shortening the syntax I didn't really understand what the point of the arrow function was?
I usually find Guil easy to understand but he completely lost me here!
Thanks for any help.
