Challenge:

Your task is to use any language to output that language's name times the number of character's in its name.

  • Use the common name or acronym of the language.
  • If there are multiple versions of a language, you need not include the version number.
  • The capitalization matters.

Examples:

PHP -> PHPPHPPHP Java -> JavaJavaJavaJava C++ -> C++C++C++ Python 3 -> PythonPythonPythonPythonPythonPython JavaScript -> JavaScriptJavaScriptJavaScriptJavaScriptJavaScriptJavaScriptJavaScriptJavaScriptJavaScriptJavaScript

You know your language is verbose when it's shorter to create an 81 character long string that it is to multiply a 9 character long string by 9.
