Class Components in React are like the older, more formal way of building things. They involve more code and can be a bit complex compared to the newer, simpler functional components. Think of them as the traditional way of doing things in React.
Limitations of class components in React:
- Confusing ‘this’ Binding: Using ‘this‘ in class components might be confusing and cause unexpected issues, especially when working with code that happens at different times or passing functions around. Users should be careful with how they connect things to avoid problems.
- Inheritance Limitations: Class components use the concept of inheritance, which would possibly lead to issues with deep aspect hierarchies and make it hard to manage state and behavior across a couple of components.
- Performance Concerns: Class components might work a bit slower than functional components with hooks because they create new instances of classes and connect methods, which can add some extra work and slow things down a little.
- Limited Lifecycle Methods: Class components have lots of ways they behave at different times (lifecycle methods), but for beginners, it can be a bit much. Not everyone uses all of them, which can make it tricky to get the hang of how a component’s life unfolds.
- Limited Reusability: Class components can be a bit harder to reuse because they follow a specific structure and rely on a method called inheritance to share behaviors. This makes it tough to mix and match component parts in a flexible and easy way.
Since functional components and hooks came into the React scene, a lot of users like them more because they’re simpler, easier to read, and handle state better. Nowadays, when we’re building things with React, these functional components are the go-to choice for most developers.
