A look at how the Call Stack, Web APIs, and Callback Queue all work together

The Event Loop is the system that JavaScript uses in the browser to handle the execution of multiple pieces of code. It consists of the Call Stack, Web APIs, and the Callback Queue. It is responsible for giving JavaScript its asynchronous programming ability.

JavaScript is a single-threaded, asynchronous language with a concurrency model that is based on a “run to completion” event loop… wait, what? Read on, and this sentence will hopefully make sense by the time you finish.

Prerequisite knowledge: basic JS functions, console.logs, and Web APIs like setTimeout and event listeners.
