  • Mapping Arrays

    Updated: 2012-08-30 03:08:28
    Say you want to double every number in a list, or transform every element of an array into something else.  You could iterate over the array and build a new array, or you could use the map method.  This is a method you really shouldn't skip learning about, it is very useful.

  • Sorting Arrays

    Updated: 2012-08-29 05:14:19
    Quick, how do you sort an array?  How you answer this depends on where you're coming from.  If you're a C programmer, you might go on about the merits of quicksort or mergesort.  If you're from C++, the standard template library has facilities for this.  But this is Ruby, how do you do it?  Well, you call the sort method, but there's slightly more to it than that.  Being a high level language, Ruby has isolated you from the sorting algorithm itself, but given you very easy sorting and a very easy way to change its behavior.
