TIOBE Programming Community Index is an indicator of the programming language trends.
It is updated monthly, this list is based on the number of experienced programmers,courses and third-party vendors on the Internet.
It uses the well-known search engines (such as Google, MSN, Yahoo) as well as Wikipedia and YouTube to calculate the ranking. Please note that this list is merely a reflection of the popularity of a programming language, does not indicate whether a programming language is good or not.
