don't use the var keyword then it will leak the var from the function scope to the global scope. edit: this is not recommended method if possible declare variables with var keyword. https://code.sololearn.com/Wr989n0MDAHh/?ref=app

@AxReal using var keyword inside the function will make the var available just to the function scope and not global scope. try my code declare the var hi in function you will understand.

заюзай var. var a = 1; var сделает переменную доступной вне функции. //не уверен, что это ещё работает. но лучше возвратить переменную. var i = 1; function test(){ var i = 2; return i; } i = test();
