 ### Explain how prototypal inheritance works
 
-This is an extremely common JavaScript interview question. All JavaScript objects have a `prototype` property, that is a reference to another object. When a property is accessed on an object and if the property is not found on that object, the JavaScript engine looks at the object's `prototype`. and the `prototype`'s `prototype` and so on, until it finds the property defined on one of the `prototype`s or until it reaches the end of the prototype chain. This behaviour simulates classical inheritance, but it is really more of [delegation than inheritance](https://davidwalsh.name/javascript-objects).
