  • PHP came down one place
  • ABAP is becoming popular
  • Python is down one place
  • Perl and Delphi goes down by one spot each

Programming languages last few months rankings:

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.
