Subject :

Your task is to use Sockets to communicate between a backend and a frontend JS applications.

Your frontend will simply send a list of texts, and your backend has to do some processing to each (say, your backend has to lowercase the text). You can add the illusion of complexity by setting a timer that runs for a certain number of seconds for each text processed, code execution can proceed after the timer is done. Example:

async function test() { console.log('start timer'); await new Promise(resolve => setTimeout(resolve, 1000)); console.log('after 1 second'); // respond to socket and repeat for the rest of the data }

The backend can keep count of how many texts have been processed so far. After the successful execution of each line of data, the backend should send a socket notification to the frontend about the number of texts processed so far. The frontend then updates the screen, showing a message like: x texts processed so far. And when all the texts are processed successfully, the frontend would display a message: Data processing complete
