Event loops are a core mechanism in programming that enables a single-threaded environment to handle multiple tasks (like handling timers, network requests, and fetching data from the internet) concurrently without freezing. It does this by continually checking if the main program has finished executing and, if so, running any pending tasks or callbacks that have been queued. You will usually witness event loops in JavaScript runtimes such as Deno, Node.js, and web browsers.
