Here we are going to have a detailed explanation of the key strengths and weaknesses of React. Before you hire a ReactJS development company for your web app project, it is important to have an understanding of these pros and cons. But it would be better if we first provide an introduction to React and its key features.
What is React, and what are its key features?
- Virtual DOM: ReactJS uses virtual DOM, which is instrumental in creating a lightweight DOM tree that can easily be saved on the server-side for faster loading time and app performance.
- One-way Data binding: The one-way data binding of React allows easy debugging, monitoring, and incorporating changes in complex and large app projects.
- Declarative UI: Thanks to this feature, there is the ease of reading React code. This results in the easy fixing of bugs.
Strengths of ReactJS
Now, let’s start our brief explanation of the strengths of ReactJS.
Lower learning curve
Easy development of dynamic apps
Often developers building dynamic web apps find the HTML strings really complicated. By using easy-to-read XML syntax through JSX, React makes it easier to handle the coding. On top of that, React’s ready-to-use components make building a dynamic UI further easier.
ReactJS uses virtual DOM, which, unlike regular DOM after updating, does not slow down the app performance. By existing entirely in the app memory, it creates a virtual copy of the DOM of the web browser. By writing and using the virtual components for the DOM, React developers ensure seamless loading and fast app performance.
Robust and ready to use tools
React is SEO optimized.
Developers also prefer ReactJS for its straightforward approach to debugging and testing. React developers, simply by using the native tools, can debug and test their apps.
Weaknesses of ReactJS
Just as the multiple strengths React framework provides, React has several drawbacks and shortcomings as well. Let’s have a look at them.
Not enough tools beyond UI development
ReactJS only encompasses the UI layer of any app. Except for UI development, all other aspects of development remain out of the periphery of ReactJS. ReactJS is incomplete as a development technology, and developers need to use other tools simultaneously.
Less evolving core
Many developers consider that the core API of React has already become very stable and stagnant, creating very less scope for changes. Most of the value additions and enhancements in React happen with React components but not with the core API. This makes React a least evolving technology. Rarely changeable.
Lack of documentation
React has a bad reputation for documentation. Since there are continuous releases of new development tools, documentation often remains the least priority. This is why developers often find it difficult to incorporate these tools in their projects.
React only takes care of the “View” part.
The model–view–controller (MVC) protocol for web UI design is preferred by developers for their comprehensive handling of multiple aspects such as API, routing, rendering, etc. But, ReactJS only takes care of the “View” part. React developers need to rely on additional tools for the other two aspects: model and controller.
