Why doesn't this array need [NSArray array]?

Question

This is a little part of the code:

int main (int argc, const char * argv[]) {
    @autoreleasepool {
        NSProcessInfo *proc = [NSProcessInfo processInfo];
        NSArray *myArray = [proc arguments];
        ...

Why isn't it written like NSArray *myArray = [NSArray arrayWithArray: [proc arguments]];? Also, with ARC does that mean arrays don't need their init methods?

Because [proc arguments]; already returns an NSArray *. Writing NSArray *myArray = [NSArray arrayWithArray: [proc arguments]]; is just redundant.
