The Modern JavaScript Bootcamp (2019) - Digging Into Prototypical Inheritance

The video tutorial explores JavaScript's prototypal inheritance, focusing on how constructor functions and prototype properties work. It explains the prototype chain, how instances link to shared methods, and the impact of modifying prototypes. The tutorial also covers property shadowing and the practical implications of prototypal inheritance, providing code examples to illustrate these concepts.

What is the significance of the 'new' operator when creating an instance of a constructor function?

How does JavaScript handle method calls on objects when the method is not found on the instance?

Describe how changes to the prototype affect instances created before the change.
