TIOBE Index for November 2019
November Headline: C getting close to Java, Swift enters top 10 and Rust scores all time high
This month there are couple of interesting moves in the TIOBE index top 20. First of all, C is getting really close to Java now. The difference is only 0.2%. May be C will become number 1 again before the end of the year. It is also exciting to see who is taking the top 10 position. This changes almost every month. Two months ago this was SQL, last month it was Objective-C, but this month Swift takes over. The gap with Ruby at position 11 is almost 0.4%, which might indicate that Swift is keeping its top 10 position at least for a couple of months. It is also interesting to note that Rust scored an all time high by jumping from position 34 to 25 in one month. If the positive news about Rust continues it might become a member of the top 20.

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.
