Code Fellows Reading Notes

Object Oriented Programming

Domain Modeling

Explain why we need domain modeling. Domain modeling allows us to create a conceptual model in code for a specific problem.

HTML Table Basics

Why should tables not be used for page layouts? Layout tables reduce accessibility for visually impaired users, tables produce tag soup, and tables are not automatically responsive.

List and describe 3 different semantic HTML elements used in an HTML table. thead, tfoot, tbody

Introducing Constructors

What is a constructor and what are some advantages to using it? A constructor is just a function called using the new keyword. When you call a constructor, it will:

• create a new object
• bind this to the new object, so you can refer to this in your constructor code
• run the code in the constructor
• return the new object

How does the term this differ when used in an object literal versus when used in a constructor? A constructor using the same code to initialize different objects, so this allows you to refer to a specific instance from the same constructor. Object literals don’t have multiple instances, so it’s not as useful since there aren’t different instances.

Object Prototypes Using A Constructor

Explain prototypes and inheritance via an analogy from your previous work experience. When you’re in a role (prototype) you inherit the responsibilities (methods and properties) of that role, but you will also have responsibilities that are specific to you that others in your role don’t share.
