The code defines a function called 'loadCharacters' that uses the fetch API to make a GET request to a local server at http://localhost:4000/characters and returns a promise that resolves to the parsed JSON response.
The code also defines a functional component called 'App' that uses React hooks to manage state. The component initializes two state variables with the useState hook - 'characterList', which is an empty array, and 'isLoading', which is set to true.
The useEffect hook is used to execute the 'loadCharacters' function when the component mounts. It updates the 'characterList' state with the data from the server response and sets 'isLoading' to false when the promise resolves or rejects.
Finally, the component renders either an image or a list of character names depending on the value of 'isLoading'. If 'isLoading' is true, an image is rendered; otherwise, a list of character names is rendered using the map function on the 'characterList' state variable.
