2021年2月编程语言排行榜（TIOBE Index for February 2021）

February Headline: it seems like nothing really changes

Some say that the IT industry is changing continuously. Every day a new IT buzzword pops up somewhere. But if we take a closer look at the top 8 of the TIOBE index, it appears to be unchanged for the last 7 years. Does this mean that the programming language world hasn't change over the last years? Of course it has changed. Except for language C, all programming languages in the top 8 are releasing new versions frequently. For instance C#, which releases a language update almost every year. Or JavaScript, which changes so fast that hardly anybody can follow. C++ is changing less frequently (once in 3 years), but its latest release contains the introduction of modules, which will cause a major shift in C++ programming.

It is interesting to note that positions 9 and 10 in the TIOBE index are not that as fixed as the top 8. Languages come and go. The last 12 months, these 2 positions were occupied by SQL, Assembly, R, Groovy, Go, and Swift. I am curious to know which of these languages will become a steady top 10 player. - Paul Jansen CEO TIOBE Software

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.
