JavaScript is fundamentally an asynchronous language. This means it can handle operations that take time, like fetching data from a server, reading files, or waiting for user input, without blocking the main thread. Asynchronous programming is crucial because it allows JavaScript to remain responsive and efficient, especially in web browsers or servers. Traditionally, handling asynchronous operations in JavaScript involved callbacks, which could lead to complicated and hard-to-maintain code known as “callback hell.” To solve this, JavaScript introduced promises, which provide a cleaner and more manageable way to work with asynchronous…

The discussion around jQuery versus React focuses on two prominent JavaScript libraries that developers use to create interactive web applications.
