Answer / Govind Singh Bonal
NSArray and NSMutableArray are classes in Objective-C to work with arrays. NSArray is immutable (you cannot add, remove or change elements), while NSMutableArray is mutable (you can modify the content). Use NSArray when you need an immutable array. Use NSMutableArray when you need to modify the contents of an array during runtime. Regarding speed, NSMutableArray is generally slower because it needs to manage both data storage and changes, while NSArray is faster since it only manages data storage.
