JavaScript is the top-ranked programming language, according to the January 2014 RedMonk Programming Language Rankings.

Since the last bi-annual RedMonk rankings, JavaScript leapfrogged Java to take the top spot, with PHP keeping its place at No. 3. Rounding out the top five, C# climbed two spots to No. 4 while Python fell a spot to No. 5. Other movers included C++ rising a spot to No. 6, Ruby falling two spots to No. 7, and CSS making its first appearance in the rankings at No. 10.

RedMonk devised the rankings by selecting and counting repository languages (excluding forks) from the top 100 languages on the two largest public development communities: GitHub and StackOverflow.
