Play

The project is build using React, one of the most popular JavaScript libraries for building user interfaces or UI components. It also uses axios, a promise-based HTTP client for the browser and node.js, commonly used to make asynchronous HTTP requests.

Main Purpose

The project sets up a fundamental playground for React, allowing beginners or developers to test and understand how React works. Its main purpose is to provide a playground platform for users to explore components and interactions in React.

Functionality

Upon execution, the function styleInject is invoked which dynamically applies a new CSS style to the entire HTML document. More specifically, it changes the background color to 'aqua'.

Next, the main component of this playground, index, is defined. React hooks are used after the component is rendered, in particular the useEffect() hook.

The useEffect() hook is used to make an axios get request to 'https://google.com'. The HTTP response data or any error is then foreseen to be logged to the console. However, in practice, this request may get blocked due to the CORS policy.

The index component itself returns a JSX structure with a header labeled as "Play" and a paragraph noting "Playground for React". This suggests that more features or functionalities are intended to be added or played with in this playground space.

In summary, the project serves as a playground for exploring functionalities of React along with other basic web technologies like HTTP GET request, dynamic CSS styling, and usage of hooks.
