Question

What’s the difference between React and jQuery?

Answer

The main difference between the React and jQuery is that jQuery is used for DOM manipulation, like modifying existing elements, and interacts with the DOM directly while React is a library for rendering and building user interfaces and interacts with what’s called the “virtual DOM”.

jQuery is not designed for building large application. We might end up with spaghetti code. its hard to deal with traditional DOM for updating.
Virtual DOM takes less time for updating. based on component, re-render particular component.

jQuery:

  • It is a utility library that simplifies complex JavaScript tasks by wrapping them into straightforward methods.
  • It is suitable for simpler tasks like building a simple website with animated navigation menus, triggering events with a button, etc.
  • It directly interacts with the DOM, which can result in lower performance.
  • It has been around for longer than React, but the number of NPM packages for jQuery is significantly low.

React:

  • It is a JavaScript library for building user interfaces (UIs) that helps developers create reusable components and handle state management.
  • It is specialized in building web apps with complicated functions and a variety of views.
  • It uses a Virtual DOM, which makes it substantially faster than jQuery.
  • It is a component management library, which is favorable for developing large-sized applications.
  • It has a larger user base compared to jQuery and dominates the USA job market.

jQuery interacts directly with the Document Object Model (DOM), which can lead to performance issues for large applications. In contrast, React uses a virtual DOM that allows for better performance and a smoother user experience.
