: Leads to "Callback Hell" (deeply nested, unreadable code) and makes error handling difficult as you must check for errors at every level. 2. Promises
The original way to handle async tasks involves passing a function (the "callback") into another function to be executed once a task finishes. : Functions are nested inside one another. Callbacks vs Promises vs Async/Await difference...
: Simple for very basic, one-off tasks; works in older environments. : Leads to "Callback Hell" (deeply nested, unreadable
In JavaScript, handling asynchronous tasks (like fetching data or reading files) has evolved from nested callbacks to more readable promises and modern async/await syntax. Each approach aims to manage the "wait time" without freezing the entire application. 1. Callbacks works in older environments. In JavaScript
