Daily Term: Callback Hell

Callback Hell

Callback Hell refers to the problem of deeply nested callbacks in asynchronous programming, making code hard to read and maintain. For example, in JavaScript, multiple nested callbacks for sequential async operations (e.g., reading a file, then querying a database) can create a 'pyramid of doom.' Modern solutions like Promises and async/await help flatten the structure, improving readability, but callbacks are still useful for simple tasks.
