Paul Jansen, the managing director of TIOBE Software in an interview with Dr. Dobbs Journal talks of the changes seen on TIOBE Programming Community Index. The TIOBE index tries to measure the popularity of programming languages by monitoring their web presence.
DDJ: Which language has moved to the top of the heap, so to speak, in terms of popularity, and why do you think this is the case?
DDJ: Which languages seem to be losing ground?
PJ: C and C++ are definitely losing ground. There is a simple explanation for this. Languages without automated garbage collection are getting out of fashion. The chance of running into all kinds of memory problems is gradually outweighing the performance penalty you have to pay for garbage collection. Another language that has had its day is Perl.
