Underscore.m, is a functional toolbelt for Objective-C. It is a small utility library written by Robert Bohnke. Designed to facilitate working with common data structure within Objective-C, its core functionality revolves around the encouragement of chaining through square brackets. Underscore.m is actually inspired by Underscore.js and utilizes a similar structure.
Underscore.m helps developers extract and capitalize strings in a simple fashion – no complexities or workarounds. Furthermore, it also allows users to deal with structured data from web APIs. It is recommended to utilize CocoaPods when installing Underscore.m for a much simpler foundation. Accessing Underscore.m’s methods concisely requires the user to alias “Underscore” to “_”. By doing so, you minimize the risk of any errors or issues occurring during the installation process as well as running the code.
Data manipulation can be a hassle. However, this utility library can manipulate data to sort and display it in a variety of ways to help run a successful website. Now Underscore has the ability to provide over 80 functions, which can perform everything from basic array mapping to inverting keys and values of an object. Versatility is the key factor in Underscore, and while not every user will find value in every single function, it’s convenient to know that there are a plethora of options for the user to choose from.
