I’m going to try to combine data from 5 different sources to come up with a unified top 10 list of programming languages for 2015:
R and VB.Net are also outliers. The former shows up as #13 on the RedMonk list, the latter at #19. R is a mathematical language, which explains why it shows up so high on the IEEE’s list. VB.NET seems to have replaced ASP.NET as Microsoft’s answer to PHP.
There are a number of languages that have fallen out of the top ten. Perl continues its long slide from top spot among the P languages (Perl, Python, PHP, and Ruby), and Objective C, the language of native IOS applications, has fallen far and fast, dropping from #3 last year on Tiobe’s list to #15 this year.
