Domain Modeling

Domain Modeling: the process of creating a conceptual model in code for a specific problem.
A model describes the various entities, their attributes and behaviours, as well as the constraints that govern the problem doamin.

A domain model that’s articulated well can verify and validate the understanding of a specific problem among various stakeholders.
As a communication tool it can be used within and between both technical and usiness teams.

Defining a Constructor and Initializing Properties

Constructor functions are defined using a function expression. Variables are declared and then assigned a function with parameters.

When a function is called, the date held inside of the parameters are stored inside the this.____ properties.
Storing data within properties ensures any newly created object can acces that data later.

AFTER the constructor function definition, obect(s) are instantiated with the new keyword and their properties are initialized by calling the constructor function. After being instantianted and initialized, these objects are stored inside the previously defined variable.

• When modeling a single entity that’ll have many instances, build self-contained objects with the same attributes and behaviors.
• Model its attributes with a constructor function that defines and initializes properties.
• Model its behaviors with small methods that focus on doing one job well.
• Create instances using the new keyword followed by a call to a constructor function.
• Store the newly created object in a variable so you can access its properties and methods from outside.
• Use the this variable within methods so you can access the object’s properties and methods from inside.
