This example demonstrates three progressively concise implementations of a React Higher Order Component (HOC), a pattern where a function accepts a component and returns a new wrapped component. The code shows both class-based and functional HOCs that render a passed component inside a `<div className="debug">` for debugging purposes. The functional versions use React component syntax with implicit returns, showing how the helper function `DebugComponent` can be defined with arrow functions. The examples highlight how React components can be composed programmatically, with the final invocation `DebugComponent(MyComponent)` applying the wrapper to any target component.

React 101

This React 101 example demonstrates a hands-on teaching environment for the React library, showcasing functional components and props through a simple todo list. The header component (`Header.js`) dynamically changes its greeting and text color based on the current hour of the day, while the main list renders three todo items from a static `todosData` array. The app uses `ReactDOM.render()` to mount the root `App` component, which combines `Header`, `TodoItem`, and `Footer` components, with each `TodoItem` receiving its data via React props. Styling is applied through a linked CSS file, and the example leverages React 16.13.1 from unpkg.

React Starter

This example demonstrates a simple React application that renders a component containing two nested `<h1>` elements repeated in two `<div>` containers. The component, defined as `App`, uses ReactDOM.render to mount it into two separate DOM elements, `root` and `root1`, which have distinct background colors defined in CSS. The code imports React and ReactDOM from their production UMD bundles, showcasing basic component structure and multiple render targets within a single page.

Basic react component

This example demonstrates how to build a minimal React application that renders a simple greeting message based on a boolean property. The code defines two components, `UserGreetings` and `GuestGreetings`, which display different heading text, with a `Greeting` component intended to conditionally render one of them. Using React 16.10.0 and ReactDOM, the app mounts a root `App` component to a `<div>` with the ID `root`. The example highlights JSX syntax, component structure, and conditional rendering logic within a basic HTML page.

React Starter - 01

This example displays a large, centered “Hello React!” message in the browser. It renders a single React component that outputs a styled div element, demonstrating the basic setup for a React application. The code uses React and ReactDOM from unpkg CDN to mount the component into the DOM root, with styling applied via a CSS class in the HTML. It serves as a minimal starter template for React-based visualizations.

React Starter

This example shows the difference between text inside JSX string literals and JavaScript expressions in a React component. The component renders two lines, one displaying the literal string `'hello'` and the other evaluating the expression `{'hello'}` to produce the same text, with distinct styling applied via CSS. It uses React and ReactDOM from the unpkg CDN, with ReactDOM.render mounting the App component into the root div, demonstrating a minimal setup for a React-based visualization or UI.

Styled-Components example

Styled-Components example shows how CSS-in-JS embeds styling directly within React component definitions, rendering a title, buttons, and a wrapper using styled.h1, styled.section, and styled.button. It demonstrates prop-based styling via interpolations in template literals, where a primary prop adapts button colors, and component extension through styled(Button) overrides. The code imports React, ReactDOM, and styled-components, then renders the composed UI into the #root div.

Hello HTML

This example demonstrates a minimal React application that renders text using JSX syntax. The page displays a simple "Hello JSX" heading inside a root div element, with the App component defined as a functional component. React 18.2.0 and ReactDOM are loaded via CDN, and the render method mounts the component to the HTML document. The body also contains commented-out SVG code showing a yellow circle with two smaller circles positioned as a face, though this is not active in the final output.

React Starter

This example demonstrates a minimal React application that renders the text "Hello React!" to the browser. The code defines a simple functional component, `App`, and uses `ReactDOM.render` to mount it into a `#root` div. It relies on the React and React-DOM production libraries, loaded via external scripts in the `index.html` file, with the custom component logic contained in a separate `index.js` file. The visualization is purely a text-based output with no data processing or graphical elements.
