Needs fixed test for 1^2^3.

• JS done, also updated to Node 12 and added truly random tests. Reference solution handled 1^2^3 wrong .. :/
• C++: TBD. Expected: equal to 123^^ Actual: 12^3^
• Python: TBD. '12^3^' should equal '123^^'
• Ruby: TBD. Expected: "123^^", instead got: "12^3^"

Everybody is popping for equal precedence even when associativity is not left. ( Well, all reference solutions. A Hell of a lot of user solution also, but not all of them. )
