2020年3月编程语言排行榜（TIOBE Index for March 2020）

March Headline: Delphi is about to fall out of the TIOBE index top 20

The end seems to be near for the well-beloved Delphi language. Delphi has been in the top 20 since the beginning of the TIOBE index (started in June 2001). In the early 2000s it was one of the most popular languages and IDEs. Borland Delphi 7 of 2002 was used by more Delphi developers than any other single version of Delphi. It was a complete environment to create Windows applications. After that Delphi got in to troubles: the port to Linux was not successful, there were some buggy releases and non-commercial IDEs with similar features started to conquer the market. In some countries, such as Brazil, Delphi remained very popular for a long time. An extra indication of Delphi's fall is the frequency of its releases. Delphi had at least one major release per year since 2001. However, the latest Delphi release is from 2018.

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.
