This is using Python 2, which is end-of-lifed. Those bare print statements are gauche. Python does have a variable keyword, `global`.

While JavaScript can omit semicolons, it's an incredibly bad idea outside of console/Node REPL. In particular it'll merge adjacent closures or constants, and you'll have an incredible time trying to find that error. Semicolon everything.

The arrow function as ()=>{} is clearer and less likely to suck up adjacent terms.

There's no point in even showing C#, since it's just Java with the capitalization swapped. Go, as well, but at least it's slightly different.

OP should learn some languages which aren't just FORTRAN-with-C-syntax, like Scheme (or any LISP), Haskell, ML, etc.
