Replicate JavaScript Constructor Inheritance with Simple Objects (OLOO)

Instructor: [00:00] If you find yourself using the new keyword a lot with functions...For example, if you did function House takes an argument of color, this.color = color. Then you did const myHouse = new House, passing in a string of "white." Then if we console.logged myHouse.color, we'd get "white."

[00:20] This probably accomplishes what you're trying to get in the end but might not be the best option. The new keyword not only calls a function but returns a new object, points the this context, and links prototypes.

[00:31] We could go about this in a different manner that is a little bit more straightforward. Instead, we can change this function to just be a regular object called House. We'll move the this.color assignment into a setter function called houseColor.

[00:44] We can change how the myHouse object's created. Instead of the new keyword, let's just use Object.create, passing through House. When we use this.colorLookup, we can pass through white. Then we see that myHouse object now has a property of color white.

[01:03] Our end result is the same. We didn't have worry about creating a function and calling it with the new keyword. This pattern is called OLOO, or objects linking to other objects.

[01:14] Since prototypes are simply objects, objects can be created in a manner so that they're easily delegated as prototypes of other objects. Object.create gives us the ability to easily create new objects that have specifically delegated prototype objects.
