Path Of The Python, Ruby, And Perl

Many programming languages were designed to promote a certain style or way of working. Python, for example, strives to provide a single ‘obvious’ path to a solution for any common problem. At the other extreme Perl seeks to provide many different ways to do something. Ruby takes a curious middle ground by providing multiple solutions yet promoting only one or two conventions.

Community is also a big factor in the way computer languages are used, developed, and taught. Within the Ruby community the Ruby on Rails has raised awareness of the convention-over-configuration paradigm.

Having a variety of shortcuts such as those in Perl and PHP have proven useful when I’m in search of a quick and dirty solution. That is likely why Perl has been so popular for getting simple jobs done.

Maintaining software as it grows and changes is one concern I have with very feature rich tools like Perl and PHP. After more than 10 years working with PHP I find I still need to check the manual to confirm behavior every single time. Javascript seems to have a similar problem, though more so because of the many different implementations.

While language usage doesn’t always strictly follow the intended usage, there are examples indicating that design philosophy impacts outcomes:

Ultimately it is up to the software engineer to decide which road to take to get to the solution. Familiarity with the platform or style is another significant factor I’ve seen at work in the mind of individual engineers.
