To create an object using the Constructor pattern, you will first need to define a constructor function.
Here is an example of a constructor function that creates an object with two properties:
In this example, the constructor function creates a CalibraintEmployees object with two properties: firstName and lastName. The constructor function takes two parameters, firstName and lastName, which are used to set the values of the properties.
To create a new CalibraintEmployees object, you can use the new keyword followed by the name of the constructor function and the arguments:
In this example, we have created two CalibraintEmployees objects: employee1 and employee2. Each object has its own properties and methods, which are independent of each other.
Here is an example of adding a method to the CalibraintEmployees object using a prototype:
In this example, we have added a getFullName method to the CalibraintEmployees object using a prototype. The method appends the firstName and lastName of the CalibraintEmployees and returns.
To use the getFullName method, you can call it on a CalibraintEmployees object:
In this example, we have called the getFullName method on the employee1 object, which returns “Lokeshkanagaraj”.
Encapsulation: Constructors encapsulate object properties and methods, making it easier to manage and manipulate related data.
Inheritance: Constructors can be used to create parent and child objects, enabling the implementation of inheritance and prototype chains.
Modular Code: Constructors help organize your code by grouping related properties and methods into a single constructor function.
Custom Data Types: Create custom data types or classes using constructors, like defining a “Car” class with properties and methods for car objects.
Code Maintainability: Using constructors makes your code more readable and maintainable by clearly defining how objects are structured.
DOM Manipulation: Constructors can be used to represent and manipulate DOM elements in web application development.
You can create an instance of an object using a constructor function by using the new keyword followed by the constructor function’s name. For example: ‘const myObject = new MyConstructor();’
