Answer / Babalu Gautam
NSArray is used when data modification is not required, as it is read-only. NSmutableArray is used for modifying the content of an array. Regarding speed, NSArray is generally faster because it's immutable, but NSmutableArray allows for dynamic changes to the data. Both are not threadsafe; they do not provide concurrent access safety.
