Code is either Lisp, or Algol-60, and Algol begat Smalltalk (object-oriented stuff). "innovative" features in well-funded programming languages, like closures or generator expressions are just features that Lisp had since 1960 and some kid finally read a history book instead of StackExchange or "Learn ${X} in 30 Days" to get a high-paying job.
PHP looks like Javascript because they're both later versions of Algol-60.
