Readings: Object-Oriented Programming, HTML Tables
Domain Modeling
- Explain why we need domain modeling.
- properly structure domain models can validate and verify the understanding of specific problem sets among various stakeholders,
- as a communication tool they define a covaulary that can be used within and between both technical and business teams
HTML Table Basics
- Why should tables not be used for page layouts?
- reduce accessibility
- produce tag soup
- not automatically responsive
- List and describe 3 different semantic HTML elements used in an HTML
<table>
<th>
table header cell: represents a cell within a table header. Defines the header of a column or row. provides context for screen readers and search engines
<caption>
represents the title or caption of a table. A brief summary or title for the table describing its content.
<td>
table data: represents a cell within a table that contains data. defines the content of a row or column within a table.
Introducing Constructors
- What is a constructor and what are some advantages to using it?
- define the “shape” of an object; the set methods and the properties it can have; then create as many objects as we like, just by updating the values for the properties that are different.
- allows us to eliminate the use of object literals when creating multiple objects.
- How does the term
this
differ when used in an object literal versus when used in a constructor?
this
in an object literal is specific to that object ONLY
this
in a constructor allows the creation of many objects that are also displaying uniquely
Object Prototypes Using a Constructor
- Explain prototypes and inheritance via an analogy from your previous work experience.
- every function in JS has a prototype property that references an object.
- prototyping allows us to share mthods across all instances of a function.
- Inheritence is inherited from the parent object just like genetics, it isn’t exactly selected
- Prototypes are traits specifically “bred” into the code for the object that are desirable and simplify/supercharge the objects
