As for ‘human’ languages, computer languages are more or less easy to learn, more or less complex to read and debug.
Some are fans of Ruby, Java, PHP or c#. Each for excellent reasons to prefer any one language to another. However, applications written in Java have more bugs that programs Erlang, PHP or C? Beyond the language theory, researchers are interested in real projects hosted by Github to evaluate the rate of bugs in the product code.
A statistical study that deals 17 programming languages
Researchers at the University of California went draw among 729 projects, 80 million lines of code, 29,000 authors and 1.5 million bids for a study statistically the bug and patches. After excluding the language of Shell, Vim and CSS, these are retained 50 large projects developed in 17 different languages. Among the projects selected, Linux, Git, Php – src for the C language, Storm, elasticsearch and ActionBarSherlock for Java, docker, lime and Websocketd for language GB or laravel, CodeIgniter and symfony for PHP.
