Is Perl obsolete? Is it worth learning Perl or it is an obsolete language and other languages should be learned instead of it? I would appreciate it if someone could shed light on this subject and give me some advices.

No. Big software isn't really efficient to develop with it, because its oop hasn't the best syntax.

And it hasn't a graph-based garbage collector and has constant (and probably forever lasting) issues with multithreading.

But: for smaller projects it is very beautiful and it can be very efficient.

It was an opinion based question, probably it will be deleted.
