    1. Introduction Microservices architecture has become a popular design choice for building scalable, flexible, and maintainable applications. Instead of a monolithic structure, applications are divided into smaller, independent services, each responsible for a specific business functionality. While this approach has many benefits, it also introduces challenges, particularly in managing communication, security, and monitoring across services.…

    1. Introduction It specifies the kinds of objects to create using a prototypical instance and creates new objects by copying this prototype. This pattern offers an alternative approach to creating new objects by duplicating or cloning an existing instance, rather than building a new one from scratch. This allows you to bypass the overhead associated…

    1. Introduction It provides an interface for creating families of related or dependent objects without specifying their concrete classes. An abstract factory is essentially a factory of factories. This design pattern encapsulates a collection of related factories that share a common theme. Instead of instantiating individual product classes directly, you create a specific concrete factory,…

    1. Introduction It defines an interface for creating an object, but lets subclasses decide which class to instantiate. The Factory Method pattern lets a class defer instantiation to subclasses. Key Features: You begin with an abstract creator class, commonly referred to as the creator, which establishes the fundamental framework of the application. The subclasses that…

Here’s a detailed explanation of their differences: preventDefault() Purpose: Prevents the browser’s default action associated with an event. Use Case: Use preventDefault() when you want to stop the default behavior of an event, such as…
