Do you have to return the inside function in order for its value to appear outside the outer function?

function dogHouse() { var dogs = 8; function showDogs() { console.log(dogs); } return showDogs; // returned here }

var getDogs = dogHouse();

getDogs();

you are right. Inside function must be returned

I'm not sure what you mean by the "value to appear outside the outer function", but if by "inner function" you are referring to "showDogs", then that function is returned by "dogHouse" (the "outer function"?) so that when it is assigned to "getDogs" it can then be invoked using that name.

If the function "showDogs" had not been returned by "dogHouse", it would not be possible to access it later.
