    In this stage, we continued our learning journey by jumping into React Components. 0:00
    Components are the building blocks of a React application, 0:05
    allowing us to create reusable and modular pieces of UI. 0:10
    To kick things off, we created our first component, the Header component. 0:14
    We discovered that defining a component in React is as straightforward 0:19
    as creating a function, with the key requirement being that 0:24
    the component names should always begin with a capital letter. 0:28
    This naming convention is crucial for 0:33
    React to differentiate between components and regular HTML tags. 0:35
    Once we created our Header component, we were ready to display it in the browser. 0:42
    Similar to HTML tags, we use the component's name as 0:48
    the JSX tag and past it to the root dot render method. 0:53
    This allowed us to effortlessly render our component on the screen. 0:58
    We repeated this process for the item and 1:04
    counter components which brought us to the concept of nesting components. 1:07
    We needed a way to render the counter component in the item component. 1:12
    React allows components to be nested inside one another. 1:18
    This nesting capability allows us to construct intricate 1:23
    user interfaces by composing smaller reusable components. 1:28
    Finally, we assembled all our components into an app component, 1:33
    forming the foundational structure of our application. 1:38
    However, our app is static. 1:42
    In the next stage, you'll learn how to insert dynamic information into 1:45
    components using properties, also known as props. 1:50
    See you soon. 1:53
