I read \"Why and how to bind methods in your React component classes?\" and grabbed the basic idea of how different is this by the scopes it gets called.
this
I
you should correct this line to
const going = some.print.bind(some);
Otherwise going is getting a different scope and its not an member of some object so this is undefined
undefined
NOTE
this refers to the current class object. And going is not a member of any class so this is undefined
going
