Answering the Front-end developer JavaScript interview questions to the best of my ability.

• Explain event delegation

Sometimes you need to delegate events to things.

• Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

• Explain how prototypal inheritance works.
