JavaScript

I'm reading the JSlint Options Documentation to understand each of the available options, and have come across one that I don't quite understand, and can't find any useful information regarding it elsewhere.

sub - Tolerate inefficient subscripting

true if subscript notation may be used for expressions better expressed in dot notation.

Can anyone shed more light as to what this means?

Thanks
