Programming languages rise and fall in popularity. For awhile everyone is keen on C, then C++, followed by languages such as Golang, Rust, Haskell, Python, or [fill in the blank with your favourite language]. Their popularity is frequently driven by need — the desire to find the best tools for highly complex programming projects.
Some languages fall by the wayside. Few programmers still use Algol, Fortran, COBOL, Basic, or Pascal. Though they were widely used in their day, they now appear mainly in legacy programs.
And some languages, while no longer as widely used, still persist among those who appreciate their special qualities. These include Common Lisp and, my favourite, Perl.
