Closing Remarks

These different indices use different bases for their rankings, so it’s rather like comparing apples and oranges. But we can still draw some interesting insights.

Once high-flying languages like Clojure, Crystal, F#, Haskell, and Nim are notably absent in the top 20 lists. TypeScript figures prominently in two lists but is absent in all the others.

It is my hope that Smalltalk will someday appear in the top 20 lists.
