Answer 1

Looks like your trying to access the result as an object. You must return the function in an object if you intend to do it in this way.

Update: cleaned up code

 const screemwarriors = () => ({ shootwarriors: () => { console.log("Ninja"); } }); const output = screemwarriors(); output.shootwarriors(); 

Cheers,

Your calling code will work if you modify your function like this:

 const screemwarriors = function() { var warriors = 'Ninja'; return { shootwarriors: function() { return warriors; } } } const output = screemwarriors(); console.log(output.shootwarriors());
