The TIOBE index is no indication of the quality of programming languages, but it aims to reflect their popularity by trying to determine how many lines of code are written in the respective languages. The data for the index is based on the number of jobs and training courses available for each language and is collected through search engines such as Google, Baidu and Bing and web sites such as Amazon and YouTube.
