How does TIOBE calculate the ranking of programming languages? _PHP Tutorial

I saw TIOBE’s programming language rankings for June on CSDN today, and I suddenly wanted to know how TIOBE calculates the programming language rankings? .

Open TIOBE’s introduction to the programming language rankings. The general understanding is as follows:

Point 1:

For a language to enter the rankings, it must meet two conditions:

Required There is a separate entry on Wikipedia, and it clearly states that this is a programming language.

Must be Turing complete.

There are currently 225 languages ​​on the TIOBE list (computer languages ​​are really broad and profound, many of which I have never heard of).

Point 2:

The language rankings (Ratings) are based on the average number of search results for this language on the 8 major websites Value, obtained by dividing the total number of search results in the top 50 languages. In CSDN terms, Ratings represent the popularity of a language.

Point 3:

Class A languages ​​are considered mainstream languages. If a language's rating is higher than 0.7% for three consecutive months, it is considered a Category A language. TOIBE recommends using Class A languages ​​to build mission-critical systems, but when choosing a language you also need to consider "suitability to the application field", "reliability of the compiler", "expression ability", "performance", and "stability".
