When a task is encapsulated into a software component, that component becomes an independent and well-understood element. Each time that component is used or reused, it performs the same task in the same way, e
The state object is used to store the data that belongs to that particular component. Functional components are stateless. It can be done via Hooks if you want to use ‘state’ in functional components. No other class can access the data stored in the state as it is private. To access t...

MEAN stack is responsible for the development of each component of website development from client-side/server-side to database handling, and all these are based on one technology, i.e., JavaScript. MEAN stack is a branch of full-stack development that is used by developers in building fast...
Let’s take an example: Look at the Facebook page, which is entirely built on React, to understand how react does works. As the figure shows, ReactJS divides the UI into multiple components, making the code easier to debug. This way, each function is assigned to a specific component, ...
In React, a component-basedarchitectureis followed, where UI elements are divided into reusable components. These components encapsulate the logic and structure of a particular part of the UI, thereby making it easier to develop and maintain complex applications. React provides a declarative approach ...
1. Component-based architecture: React encourages the creation of reusable components, which makes it easier to maintain and scale applications. Components are self-contained, modular pieces of UI that can be combined to create complex interfaces. ...
styleUrls: ['./app.component.css'] }) export class AppComponent { user = { name:'Rohit', age: 23}; } In the above example if user name or age change then pure pipe can not detact the change and execute. Impure Pipes:An impure change is when the change detection cycle detects a ...
