What is an event loop?
You’ve probably heard this term before, but maybe you didn’t fully understand the meaning and purpose behind it. As a new web developer, the almighty event loop will be your best friend at work for many years to come…unless you have a generous co-worker who brings in gourmet coffee every morning.
Event loops are really the bread and butter of your application. They tie everything together from the moment you receive a page request until the web server returns a response to the browser.
