React Version Major Differences
React 0.x
  • React 0.x introduced the concept of components, allowing developers to build reusable UI elements.
  • It used the createClass API to define components.
  • React 0.x had a virtual DOM implementation that was not as efficient as later versions.
  • It did not support server-side rendering.
  • React 0.x had limited performance optimizations compared to later versions.
React 15.x
  • React 15.x introduced the concept of stateless functional components, allowing developers to write components as pure functions.
  • It introduced the PureComponent class, which provided a performance boost for components that only rely on props and state.
  • React 15.x improved server-side rendering support.
  • It added the ability to return arrays of elements from render methods.
  • React 15.x deprecated some older APIs and introduced new lifecycle methods.
React 16.x
  • React 16.x introduced the concept of error boundaries, which allowed developers to catch and handle errors in a more controlled manner.
  • It introduced the Fiber architecture, which improved the performance of rendering and reconciliation.
  • React 16.x added the ability to return strings and numbers as children of components.
  • It introduced the new Context API, which made it easier to share data between components without using props.
  • React 16.x added support for portals, allowing components to be rendered outside of their parent component hierarchy.
React 17.x
  • React 17.x focused on improving the upgrade process for existing applications.
  • It introduced a new JSX transform that removed the need for importing React in every file.
  • React 17.x made changes to the event system to improve consistency and performance.
  • It improved the error messages and warnings to provide more helpful information for developers.
