A popular programming language Perl is celebrating its 25th anniversary. The first version of Perl Larry Wall was released December 19, 1987. Larry Wall is not a mathematician or a programmer, a linguist, for creating a language he offered some unusual design, which differs sharply from the popular Perl while low-level languages. itself language Perl is a high-level, that is, its source code is not compiled into binary files, and are not given directly to the processor, and run through the interpreter (as well as PHP, JavaScript, Python, etc.). Additional layer in the form of an interpreter, of course, reduces the performance of the program, but the high-level languages have a clear structure, easy to read and can be used even not very experienced programmers.
Basic feature of language is its rich opportunities to work with text, including work with regular expressions, built-in syntax. Pearl has inherited many features of the C language, AWK, scripting languages shells UNIX. Perl is also famous for a huge collection of additional modules of CPAN, located at http://www.cpan.org . Language name is an abbreviation which stands for Practical Extraction and Report Language - «practical language for data retrieval and reporting." Originally abbreviation five characters in this form coincides exactly with the English word pearl («Pearl"). But then it became known that such language exists (PEARL (English)), and the letter «a» removed.
The main advantages are the support for different language paradigms (procedural, object-oriented and functional programming styles), control of memory (without garbage collection, based on cycles), built-in word processing, as well as a large collection of third-party modules.
