An event loop is a programming construct that allows programs to handle and process multiple events, such as user input, system events, or network messages, in a non-blocking and asynchronous way. Event loops are commonly used in web development to handle user interactions, server requests, and other types of events that can occur concurrently or unpredictably. Event loops can improve web application performance, scalability, and responsiveness, by reducing the amount of idle time and by allowing multiple tasks to be executed in parallel. Event loops can be implemented using various programming languages, such as JavaScript, Python, or Ruby, and can be supported by different frameworks, such as Node.js, React, or Flask.
