Introduction One of the ideas in JavaScript that I think most beginners struggle with is asynchronous programming. I struggled to understand it as well. It took some time for me to finally grasp this notion, despite the fact that I saw a number of tutorials and read a lot about it. In order to make asynchronous JavaScript easy to comprehend for novices, I will do my best to describe it in this essay.   JavaScript is a single-threaded programming language which means only one thing can happen at a time. That is, the JavaScript engine can only process one statement at a time in a single thread. While the single-threaded languages simplify writing code because you don’t have to worry about the concurrency issues, this also means you can’t perform long operations such as network access without blocking the main thread. Imagine requesting some data from an API. Depending upon the situation the server might take some time to process the request while blocking the main thread maki
