Java is the most popular programming language in the world, according to the latest TIOBE Index, with C, C++, C#, and Python rounding out the top five (in descending order).
TIOBE, which updates its rankings once a month, bases its index on search-engine data; featured languages must have an entry on Wikipedia, be Turing complete, and at least 10,000 hits for +“<language> programming” on Google.
“Java and C appear to be the 2 big languages at the moment,” read the note accompanying TIOBE’s data. “The gap between these 2 and the rest of the pack is now more than 10 [percent].”
Speaking of Swift, the next-generation programming language now stands at 15th place on the TIOBE Index, nearly on the verge of overcoming Objective-C, its predecessor, which occupies the 14th slot. Last year, Objective-C ranked third; it remains to be seen whether Swift will climb that high, although the popularity of the iOS and Mac OS X platforms (the primary targets of apps built in Swift and Objective-C) bodes well for its chances.
