What is the weakness of ReactJS? ›

Drawbacks of ReactJS:

Learning curve. Being not full-featured framework it is requered in-depth knowledge for integration user interface free library into MVC framework. View-orientedness is one of the cons of ReactJS.

Problem 1: State Management

React applications often require managing various types of data and state. As your application grows, handling state efficiently across components can become challenging.

Disadvantage of ReactJS

They need to be always updated with their skills and learn new ways of doing things. It is another cons which are common for constantly updating technologies. React technologies updating and accelerating so fast that there is no time to make proper documentation.

Flexibility in the organization of code makes it harder to understand code. This can be difficult when analyzing a project you are unfamiliar with. React only covers the UI components, nothing else. Developers spend more time configuring supportive tools.

Functional components cannot use React lifecycle methods, such as componentDidMount. Class components can use React lifecycle methods (for example, componentDidMount, componentWillUnmount etc). There is no use of constructors. Since the state needs to be stored, constructors are utilized.

You might want to learn React but worry that it could be too hard. Thankfully, React is easy to learn, but only once you have foundational knowledge in JavaScript. Of course, the difficulty that comes with learning anything new is somewhat subjective.

This is due to its modular nature. Most React modules are interrelated and require you to use other software to build a complex application. You'll also need knowledge of functional programming. You need to know the concepts of curried, immutable, and higher-order functions, which are useful for React.

What are the limitations of ReactJS Mcq? ›

React is a good fit for projects with multiple state changes that are intertwined and dependent on each other. Changes are tracked on the virtual DOM and then applied to the real DOM, ensuring that React uses the virtual DOM to keep track of changes in the application, then updates the real DOM with those changes.

Side Effects (in function components)​

Data fetching, setting up a subscription, and manually changing the DOM in React components are all examples of side effects. Whether or not you're used to calling these operations “side effects” (or just “effects”), you've likely performed them in your components before.

Large-scale applications

React's component-based architecture allows you to create modular and reusable code that can help you scale your web application as your business grows. This makes React a great choice for developing large-scale applications that require maintainability, scalability, and flexibility.
