Perl v5 is a high-level general purpose programming language invented by Larry Wall and first released in 1987. It is an eclectic interpreted, procedural, loosely typed language. Its popularity peaked with the rise of the World Wide Web, though it remains widely used in Quality Assurance, IT infrastructure automation, text processing, bioinformatics and web application development, just to name a few areas. It is highly flexible, but this flexibility can have a follow-on maintenance cost.

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.
