    Congratulations on completing your first stage of your React learning journey, 0:00
    in this stage we focused on setting the foundation for 0:05
    React by building a solid understanding of its core concepts. 0:08
    We learned that React is a JavaScript library for 0:12
    building user interfaces, it allows us to create reusable, and 0:16
    modular UI elements making our code more maintainable and efficient. 0:20
    I then focused on getting you all set up to code along with me, we went through 0:25
    all the files in the project and showed you how to set up the development server. 0:31
    Initially, there was nothing visible in the browser since our 0:36
    main.jsx file didn't contain any React elements. 0:40
    To address this, we took our first steps into creating React elements using JSX, 0:46
    an extension of JavaScript that allows us to write HTML-like syntax within our code. 0:52
    We learned that React elements are plain JavaScript objects that describe 1:00
    the elements to be displayed in the UI. 1:05
    In order to see our React elements on the page, we covered the essential 1:08
    step of rendering these elements using the createRoot and root.render methods. 1:14
    These lines of code are crucial, as they ensure our React elements 1:21
    are properly rendered to the DOM, making them visible in the browser. 1:25
    Continuing our exploration of JSX, 1:31
    we discussed the three fundamental rules of JSX. 1:33
    Return a single root element, closing all the tags and 1:38
    camelCase all most of the things. 1:43
    Furthermore, we learned how to embed JavaScript 1:47
    code within our JSX syntax through JSX expressions, 1:51
    this powerful feature allows us to dynamically generate content and 1:55
    perform calculations directly within our JSX element. 2:01
    We covered a lot of ground in this stage, establishing a strong foundation in React, 2:07
    if you feel the need for a refresher, don't hesitate to revisit those videos. 2:12
    In the upcoming stage of our learning journey, 2:18
    we'll be writing React components, which are at the heart of React. 2:21
    I'll see you in the next video. 2:26
