Creating arrays sections needs explanations: why is the array-literal preferable? why do we need to be able to recognize the archaic forms? Why can't an array contain 'nil'?
Include [NSArray count] explanation.
Explain that arrays can contain other arrays (array-types like dictionaries and stacks). The term for this is "nested", but "nested arrays" functionally form a matrix.
There is a link to the NSSortDescriptor lesson. Should this be removed or revised as advanced reading for future use?
Methods listed should be explained better, and a link to the NSArray Apple Doc should be included.
Needs some love.
Formatting/style consistency.
