- Basic knowledge regarding the use of npm.
- Understanding of ESC6.
What is ReactJS used for?
MVC: Model View Controller, popular as MVC, is a software architectural pattern commonly used for designing and developing UI (User Interfaces). It helps to divide the related program logic into three interconnected elements, i.e., Model, View, and Control. The use and benefits of react js are given below:
Creation of Dynamic web applications
Helps to build rich user interfaces
Nowadays, the quality of User Interface (UI) for web applications plays a very important role. One of the determinant factors for a web application to succeed is the high-quality design of the UI. If the UI is highly designed, there is a high chance of user retention in the web application. React js allows the developer to develop the web application using declarative components.
Dedicated tools for easy debugging
Social media giant Facebook has released a Chrome extension that developers can use to debug React applications, which helps to make the processing of debugger React applications easier and faster.
For the fast rendering of the Application
When building a complex high-load web application, defining its structure at the beginning is mandatory because it highly impacts the Application's performance. As Facebook has introduced the virtual DOM feature, the virtual representation is the tree-structure model that allows testing all changes first to calculate risk with each modification. It is the modern approach to maintaining a high web application performance guarantee and good user experience.
Example of ReactJS
Suppose you're using Facebook; on a newsfeed, you've seen your friend post an image. You liked the image, entered the comment section to comment, and started viewing others' comments. While browsing the comment section, you've found that the digit of like and reaction is increased without reloading the page. That magical change is the result of ReactJS.
Why is React such a good start for beginner developers?
Scope in React.js as a fresher
One of the important elements of successful web applications is their User Interface (UI) design. React js developers are responsible for designing the user interface. With the constant increase in the number of web applications in Nepal, the scope of React.js developers is gradually increasing. In the context of Nepal, React.js as a fresher is a good initiation. Whether you can join as a developer affiliating with a company for an internship or can do freelancing work, both are going to be worth it.
