Domain Modeling

Explain why we need domain modeling.

Domain Modeling is a way to describe and model real world entities and the relationships between them, which collectively describe the problem domain space. Derived from an understanding of system-level requirements, identifying domain entities and their relationships provides an effective basis for understanding and helps practitioners design systems for maintainability, testability, and incremental development.

HTML Table Basics

Why should tables not be used for page layouts?

1. Layout tables reduce accessablity
2. It’s a mess of tags that can make it difficult to read and maintain
3. Tables are not automatically responsive in regards to layout

List and describe 3 different semantic HTML elements used in an HTML <table>.

<table> this is the tag to initiate the table.

<td> means ‘table data’, it translates to being a cell within the table.

<tr> means ‘table row’ and it tells the computer that it’s time to start a new row, grouping the cells together in a line.

<th> means a ‘table head’ which can be used as a catagory, they have intrinsic values built in such as being bolded and centered.

Introducing Constructors

What is a constructor and what are some advantages to using it?

A constructor is a special function that creates and initializes an object instance of a class. In JavaScript, a constructor gets called when an object is created using the new keyword. The purpose of a constructor is to create a new object and set values for any existing object properties.

The advantage to using a contructor is that you don’t have to recreate a unique object every time you want to add one. If they are all structured the same you can just use a constructor with the new information to create another object.

How does the term this differ when used in an object literal versus when used in a constructor?

It binds ‘this’ to the new object, so you can refer to ‘this’ in your constructor code.

Object Prototypes Using A Constructor

Explain prototypes and inheritance via an analogy from your previous work experience.

NOTE: This is a very common front end developer interview question

In the spirit of describing the kitchen through the eyes of prototypical inheritance: while everyone in the kitchen may be a line cook, not all the line cooks can be a saute station line cook. Even saute station line cooks are not the sous chef.
