全球最热门的编程语言20种
The   TIOBE   Programming   Community   index   gives   an   indication   of   the   popularity   of   programming   languages.   The   index   is   updated   once   a   month.   The   ratings   are   based   on   the   world-wide   availability   of   skilled   engineers,   courses   and   third   party   vendors.   The   popular   search   engines   Google,   MSN,   and   Yahoo!   are   used   to   calculate   the   ratings.   Observe   that   the   TIOBE   index   is   not   about   the   best   programming   language   or   the   language   in   which   most   lines   of   code   have   been   written.

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.
