Pros and Cons of ReactJS
ReactJS is the most widely used open-source JavaScript library today. The main goal of ReactJS is to develop a user interface (UI) that increases the speed of your application.
Benefits of ReactJS.
1. Easy to learn and Use.
ReactJS is easier to learn and use. It has good documentation, tutorials, and training resources; any developer with a JavaScript background can easily understand it and start building web applications with React within a few days. It is the v (exposed) part of the MVC (Model-View-Controller) model and is called “one of the JavaScript frameworks”. Although not fully functional, it is an open-source JavaScript (UI) library that has the advantage of making tasks easier to perform.
2. Makes it easy to create Dynamic Web Applications.
It was difficult to build a dynamic web application that references HTML strings because it requires complex coding, but React JS solves this problem and makes it easy to build.JSX (JavaScript Extension) is an extension to JSX that allows you to add specific subcomponents to It uses a special syntax that uses HTML quotes and HTML tag syntax to render certain subcomponents. It also supports the creation of machine-readable code.
3. Reusable Components
ReactJS web applications are built from multiple components, each with its own logic and controls. These components are responsible for producing a small reusable piece of HTML code that can be reused anywhere. Reusable code makes your application easier to develop and maintain. These components can be nested with other components, allowing you to build complex applications from simple building blocks. ReactJS uses a DOM-based virtual engine to place data in the HTML DOM. By only modifying individual DOM elements instead of reloading the entire DOM each time, the virtual DOM works quickly.
4. Performance Improvement.
ReactJS improves performance with the virtual DOM. The DOM is a platform-independent programming API that works with HTML, XML, and XHTML. ReactJS solves this problem by introducing the Virtual DOM. React’s virtual DOM resides entirely in memory and represents the web browser’s DOM in memory and represents the web browser’s DOM in memory. So when we write components in React, we don’t write directly to the DOM. Instead, we get smoother and faster performance by writing virtual components that are converted to the DOM in React.
5. Support for Practical Tools
React JS is also gaining popularity because it comes with a set of useful tools. These tools make the developer’s job easier: with React Developer Tools, a developer extension for Chrome and Firefox, you can view the hierarchy of React components in the virtual DOM. You can also select a specific component to examine and edit its current props and state.
6. Known to be SEO-friendly
Traditional JavaScript frameworks have a problem with SEO. Search engines usually have trouble reading applications that use a lot of JavaScript. Many web developers often complain about this problem; ReactJS overcomes this problem and makes it easier for them to find you on various search engines. This is because the React.js application runs on the server, makes the DOM virtual, and returns it to the browser as a normal web page.
7. Advantages of the JavaScript library
Currently, ReactJS is the choice of most web developers. This is because it provides a very rich JavaScript library; the JavaScript library gives web developers more flexibility in choosing the form they want.
8. Code Testing Area.
Testing a ReactJS application is very simple. It provides an area where programmers can use native tools to test and debug their code.
Disadvantages of ReactJS
1. Fast development speed
The fast development speed has both advantages and disadvantages. The disadvantage is that the environment changes so quickly that some developers are not willing to learn new ways of doing things on a regular basis. With all the constant updates, it can be difficult for them to adopt these changes. They have to learn a new way of doing things with their existing skills.
2. Insufficient documentation
This is another common disadvantage of constantly updating technology. Responsive technology updates and accelerates so quickly that there is no time to create proper documentation. To overcome this, developers write guides for themselves as they develop new versions and tools for their current projects.
3. Look at the Parts
ReactJS only covers the UI layer of the application and nothing else. So to get a complete set of tools for project development, you need to choose some other technologies.
4. JSX as a barrier
ReactJS uses JSX, a syntax extension that allows you to mix HTML with JavaScript. While this approach has its advantages, some members of the developer community see JSX as a barrier, especially for new developers. Developers are frustrated by the complexity of the learning curve.
Wrapping Up -
considering the pros and cons of React Js, it can be said in three words; responsive, advanced, non-risky. It can be a reasonable choice for both startups and enterprises. you can also hire react developer for top react development companies in India.
