Gain insights into writing cleaner, modular, scalable JavaScript code through OOP. Explore basics to advanced concepts like prototypal inheritance, method overriding, and ES6 features.

Learn to write cleaner, more modular, and more scalable code in JavaScript by gaining mastery of Object Oriented Programming (OOP). 

You'll start with the basics of object-oriented programming and build up to more advanced concepts such as prototypal inheritance, prototype chaining, method overriding and mixins. Along the way, you'll learn how each concept applies to JavaScript's sometimes unique way of handling things. You'll also see how various JavaScript features make it particularly convenient for OOP, with particular emphasis on changes introduced in ES6.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

Learn Object-Oriented Programming in JavaScript

Let's discuss how to create objects using the *constructor function*.

function Employee(_name, _age, _designation){
  this.name = _name
  this.age = _age
  this.designation = _designation
}

# Creating an Object Instance 
Every time a *new* *object* is created, it is referred to as a new *instance*. Multiple object instances can be generated using constructor functions.

# Syntax

Let's take a look at the syntax for creating an object:

var ObjectName = new ConstructorFunction(argument1, argument2,....)

## Explanation

* The *keyword* `new` is used to create a new object.

* That is followed by the *constructor function* being called with the required *arguments* passed into it. This is why the code in the *constructor function* executes every time a new object is instantiated.  

*  An object will then be returned which will be stored inside a variable, that is, `ObjectName` in the above case.

* Each *new* object created will store the argument values passed into the constructor function.

This lesson teaches us how to create object instances using constructor functions by explaining the syntax and giving an example.
