When you're learning Perl, it's hard to care if Perl is obsolete. Is this version already obsolete?
For the previous question, it may be useful to refer to the February 2012 Tiobe report, according to which we can see that Perl has been a downward trend since 1997, but we can also see that Perl has been in the top 10 since 1997, and Perl has been steadily rising in the last year.
TIOBE programming language Community rankings are an indicator of the trends in programming languages and are updated monthly. The rankings are based on the number of experienced programmers, courses and third-party vendors on the Internet. The rankings are calculated using well-known search engines (such as Google, MSN, Yahoo) and Wikipedia and YouTube. Note that this list only reflects the popularity of a programming language and does not explain how well a programming language is, or how much code is written in a single language.
For the latter problem, the programming language is to solve the actual problem, the development environment should be consistent with the production operation environment. If there are no restrictions, the latest version is usually the best.
We can find many things about Perl and other languages on the web. Here I would also like to express a few points: one, what language is more depends on the project rather than on the hobby; the development of programming ability will definitely break through the limitations of the language itself, which is not contradictory to a particular language; third, we should cherish the opportunity to use each language; The old version may not be practical enough, the historical and cultural flavor is not replaced by the new version.
