How the way of writing asynchronous code in JavaScript has changed with the development of the language
The article discusses the evolution of asynchronous operation in JavaScript, tracing its journey from the early days to the present. It begins with the classic implementation of asynchronicity using callbacks, which could lead to the infamous 'callback hell'. The next section introduces the introduction of Promises, which greatly simplified the handling of asynchronicity. Promises eased the developer's burden when working with operations that allow for delays, as they provide a better structure for chaining operations. The author then covers the introduction of async/await in ES2017, which revolutionized the way developers handle asynchronous operations, enabling more readable and organized code. In conclusion, the article summarizes the changes that have taken place and their significance for the future of JavaScript, alongside potential plans for new features in this programming language.
