Create an empty dictionary, [NSDictionary dictionary] vs @{}, [NSArray array] vs @[], [NSString string] vs @""

Question

[NSDictionary dictionary] is the same that @{} in terms of memory usage?

Which one should I use?

This same logic applies to [NSArray array]/@[] or [NSString string]/@""?

Thanks!

One is nothing more than a convenience for the other. Syntactic sugar. — mah, Apr 22 '14 at 00:29
Even if they weren't equivalent: why would you worry? Did you benchmark your code? Did you find that creating dictionaries and arrays eats up tremendous amounts of your memory? — The Paramagnetic Croissant, Apr 22 '14 at 18:06

It does not matter which you use, they are effectively the same.
