split function behavior differences
   A little note from my debugging experience. Split function works differently and I would say unexpectedly for empty string in different programming languages, and it can cause difficult to find bugs (especially if you use a lot of languages simultaneously).   I've created a table with the popular programming languages:    Language Split without parameters Split with parameter  Python ''.split()=[] ''.split(',')=['']  Ruby ''.split()=[] ''.split(',')=[]  JavaScript ''.split()=[''] ''.split(',')=['']  PHP N/A explode(',', '')=array(0=>'')  Java N/A "".split(",")={""}  C# "".Split()={""} "".Split(',')={""}     As you can see sometimes it returns empty array, but sometimes an array with the one empty element. So please be careful with the split operation :)
