PopularitY of Programming Language (PYPL) is a very popular reference metric. The ranking of its ranking data is based on the relevant search frequency of the list object on Google. The original data comes from Google Trends, which means that a language or an IDE is on Google. The higher the search frequency, the more popular it is. Developers can use PYPL as a reference to decide which language or IDE to learn, or which language or database to use in a new software project.
We can also observe that in addition to Python, other recent popular languages are mostly showing a rise in the list, such as Rust, Go, TypeScript and Kotlin, although there are only minor changes compared to the same period last year. The Kotlin share has remained stable since it jumped from 0.94% to 1.4% in June, and it currently has three green arrows in the list.
