JavaScript Asynchronous Programming

JavaScript is single-threaded, meaning it can only execute one task at a time in a specific order (synchronously). However, it supports asynchronous programming to handle tasks like fetching data or waiting for a timer without blocking the execution of other code. This allows JavaScript to remain responsive and efficient, even during long-running operations.

Asynchronous programming

Asynchronous programming allows JavaScript to handle tasks without blocking the execution of other operations. This is particularly useful for time-consuming operations, such as fetching data from an API or reading files, as it keeps the application responsive and efficient.
