Answer / Ankur Sudhanshu
Objective-C blocks (also known as closures) are self-contained chunks of functionality that can be passed around and used in your code. They allow you to write anonymous functions, which can capture and store references to any constants and variables from the context in which they were created. Blocks are useful for creating callbacks, handling asynchronous events, and implementing custom algorithms.
