JavaScript and React.js are two related but distinct concepts: JavaScript: - A high-level, dynamic, and interpreted programming language - Used for client-side scripting on the web - Allows developers to add interactivity, animations, and dynamic effects to websites - Can be used for both front-end and back-end development (with technologies like Node.js) React.js: - A JavaScript library for building user interfaces (UIs) - Developed by Facebook (now Meta) for building reusable UI components - Allows developers to create declarative, component-based UIs - Focuses on building fast, scalable, and maintainable UIs In short, JavaScript is the language, while React.js is a library built on top of JavaScript for building UIs. You can use JavaScript without React, but you can't use React without JavaScript. Think of it like building a house: - JavaScript is the tools and materials (hammer, nails, wood, etc.) - React.js is the blueprint and framework for building the house (pre-designed structures, templates, etc.) I hope that helps clarify the difference!
