# Asynchronous JavaScript
 
Asynchronous JavaScript allows code to start long-running operations, like network requests or timers, and continue executing other code while waiting for them to complete. JavaScript is single-threaded, so asynchronous patterns prevent the main thread from blocking. The main mechanisms are callbacks, Promises, and async/await.
