Overview
When many objects of the same type need to be created, an “object type” can be be created using an object constructor function.
Creating an Object Type
function Car(type, model, year) {
this.autoType = type;
this.autoModel = model;
this.autoYear = year;
}Note
In the constructor function, “this” has no value. The value of “this” will become the new object when a new object is created.
Note
It is good practice to name constructor functions with an upper-case first letter.
Creating the Many Objects
The new to create many new objects based on the object type.
const myNewCar = new Car("Maserati", "Quattroporte", 2019);
const myOldCar = new Car("Alfa Romeo", "Guilia", 2019);
const myOlderCar = new Car("Maserati", "Ghibli", 2016);JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- JavaScript variables are case sensitive (x is not the same as X)
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
