JavaScript's - class, constructor, methods

 JavaScript's (OOJS)



Today's topic - javascript class, constructor, methods


What are classes?

If i say in really simple words classes are the blueprint/template for creating objects. As you wish to call them, by using classes we can make a reusable block of code which we can use anywhere in our current project or in any other project where we need the same functionality.

Classes in javaScript are built based on prototypes.


Defining classes - 

Classes are basically the same as functions or you can also say they are a kind of special functions. 

So basically the classes have three parts as follows:


  • Class creation 

You can use the class keyword to create a new class followed by the class name.

Eg - Class creation.

  • The constructor method

So basically constructor is a special method of class. It is executed automatically when the object is created. The use of constructor is to initialize object properties.

constructor is created using the keyword constructor.


Eg - constructor method.


  • Class methods 

Class methods are just the same as object methods. Once you create a class you can use as many methods as you want in a single class. 


Eg - Class method.



Summary of today's post 


  • Classes are the blueprints to create an object and classes can be created using the class keyword.

  • Constructors are used to initialize objects and constructors can be created using the constructor keyword.

  • Class methods are just the same as object methods. Executes the code in them when they are called.





That's all for today, Hope you learned something.

have a beautiful day ❤

JavaScript - Arrays

Image
  JavaScript Arrays Today’s topic JavaScript arrays and some of its most used methods. What are Arrays ?  Arrays re used to store more than one value at a time Arrays are special variables.  Syntax: const array_name = [ n 0 , n 1 , n 2 , n 3 , n n ]; Eg: This is the basic way for creating an array.  Types of arrays (1) Uniform -  An array which has a single type of data. Eg - Uniform array. (2) Un uniform - An array which has multiple types of data. Eg - Un uniform array. (2) Dimensional Array - A simple description would be the 2D Array are Arrays of Arrays.  Eg - 2D array. The Array.from( ) :   It takes an array-like object & turns it into a complete array, or you can say does a shallow copy. In which you can perform all array functions.  Syntax : Array from (arrayLike, mapfn, thisarg)  arrayLike An array-like or iterable object to convert to an array . mapFn Optional Map function to call on every element of the array . thisArg ...

javaScript's - inheritance, super keyword, new keyword

Image
JavaScript’s (OOJS) Today’s topic - Inheritance, Super keyword, New keyword. Inheritance -  Inheritance basically means to create a child class which has access to a parent class or base class. The child class inherits all the methods from its parent class.  To create a class inheritance we use the Extends keyword. Inheritance is basically great for code reusability.  WHY? Because  you can use the properties and methods of the parent class in the child class. Super keyword -  So basically the super() keyword is only available to classes. The super() always refers to the parent class constructor. By calling the super() method in the constructor of the child class you call the parent class constructor and get access to parent properties and methods. If there is a constructor in the child class the super() method should be used before this() keyword otherwise it will cause a reference error. New keyword -   The new keyword is basically used to create an i...

javascript's - this keyword, getters & setters, Dom box dimension properties

Image
  JavaScript Today’s topic - this keyword, Getters & Setters,  Dom box dimension properties. This keyword this keyword’s  simple description would be it refers to the object in which it is used. this can give different values based on where it has been used. Global context - In global context  i.e used outside of any function this will refer to the global object. this in a global context. Function context - When this keyword is used in the function in non strict mode this will refer to the global object . this in a function context. Function context (“strict mode”) - When  this keyword is used in the function context in strict mode this will be undefined. this in a function context using strict mode. Method context - While used in method context this refers to the owner of the method in which it is used. this in a method context. Event context -   When used in an event context this will refer to the element by which the event is called. this...
