Underscore.m

Enables readable method chaining for data operations, as shown in the example with .filter, .reject, and .map, reducing the verbose square bracket syntax typical of Objective-C.

Includes helpers like Underscore.isDictionary to ensure operations are performed on expected data types, preventing errors when handling dynamic API responses.

Works seamlessly with JSON data parsed via NSJSONSerialization, making it ideal for real-world API processing, as demonstrated in the twitter search example.

Encourages a more expressive style by eschewing excessive brackets, simplifying complex data transformations into clean, chainable calls.
