4 Ways to Create An Object In JavaScript:-JavaScript is a object oriented programming language. It is designed as a set of objects that interacts with each other. Object oriented programming languages like as C++, Java Script, Ruby on Rails address the shortfalls of procedural language like C or Pascal that focus on procedures and actions instead of objects. In JavaScript you can make a object through several ways. SO here we come with this post of 4 Ways to Create An Object In JavaScript.
What is a JavaScript Object?
JavaScript object is a variable that can hold many different values. It acts like a container of set of related values. For instance a website user payments in a back account or recipes in cookbook could all be is JavaScript Objects.
JavaScript objects can store two kinds of value:
- Properties for static value
- Methods for dynamic value
While you create JavaScript object you need to define its name, methods & properties.
Create a JavaScript Object:- JavaScript object can be made in four different ways.
- With Object Literals
- Using Constructor Function
- With ECMAScript 6 Classes
- With Object.Create(Method)
4 Ways to Create An Object In JavaScript
- With Object Literals:-This is a simplest way to create JavaScript object. As objects are variables you can build them in same way as variable. If you open console in your web browser you can use the console.log () function to test if the object has been created really. Also you can check the property safely by calling its names using dot notation. You can’t only define simple values for properties. It’s also possible to make use of objects as properties of objects. This feature is useful when you want to structure the data your object stores.
Object literals are examples of JavaScript’s global object() object type. JavaScript has number of built-in objects like object() and Array() that have their own pre-defined properties & methods.
- Constructor Function:- second method of creating JavaScript object is constructor function. Similar to object literals here you can define object type without specific values. Then you can build new object examples and populate them with different values. Additionally you can also define methods within constructor function. You need to use the approx same syntax of methods created for object literals. Only difference is that here you can also add this keyword before the name of method. When you test results in console it returns the same result as before.
- ECMASCRIPT 6 CLASSES:- ECMAScript introduce a new syntax for building JavaScript object- class syntax. Although JS is object oriented language. Before ES6 it didn’t use classes as other languages of OOPs. The new class syntax doesn’t add any logic to JavaScript it is nothing more than syntactical sugar. But it’s a nice feature if you are coming from another oops languages & missing old ol’ class syntax.
- The OBJECT.CREATE () Method:- the last & final way to create JavaScript object is Object.create() method. It is standard way of JavaScript’s pre-built object type. The Object.create() method allows you to use existing object literal as an prototype. Objects created with Object.create() method are also object literals and the example of JavaScript’s built-in Object() object type.
