JavaScript Classes

#javascript #javascriptclasses
Hello there! The topic is classes.
This is a tutorial about how we declare classes.
First we use class keyword then we write name of the class.
Always use upper camel case for class names.
A constructor is called when an object generated from a class.
We can use a class as a template to make an object.
Classes are templates for generating objects.

What is "this" keyword refers to in classes?
if you declare an object named tesla "this" keyword refers to tesla.
If you declare an object named honda "this" keyword refers to honda.

You can see all these topics that I mentioned in the video.

Upper camel case is also called Pascal Case

In reality this has no value until you are able to map such objects to a Database so that they persist and be able to run complex queries and perform CRUD operation efficiently and effectively. In all other cases it's just really cool, nothing much!

Imagine you are dealing with hundreds of thousands of such objects, this is what you need to provide such a solution for.

Is it only enough to learn about the classes?.

[rubiusoficial]

So "this" is only needed for declaring object properties for constructors but not needed for creating NEW instances of a constructor? am i right?

What happens if you didn't use the new keyword? Is it a must?
