- HTML
- CSS
- JavaScript
React is a JavaScript library for building dynamic and Interactive user interfaces. It was created at Facebook in 2011, and is currently the most widely used JavaScript library for frontend development.
Well, as we probably know, when a web page loaded in a browser, the browser takes the HTML code and creates a tree like structure called the document object model or the DOM for short. This allows us to use Jasvascript and change the page content in response to user actions.
For Example, we can use JavaScript to hide an element when a button is clicked. This is called vanilla JavaScript, meaning plain JavaScript code without any third party tools. Now, as our applications grow, working with DOM can become quite complex and challenging to manage. This is where react comes into play. With react, we nolonger need to worry about querying and updating DOM elements, instead, we describe a webpage using small reusable components and react will take care of efficiently creating and updating DOM elements. So components help us write reusable, modular and and better organized code
We can build all these components individually, and then combine them to build page. Essentially, a React application is a tree of components with the app being the root, bringing everything together.
