Is calling a function that returns a function with new different than just invoking it normally?

Question

So let\'s say I have a javascript function

function A(){
    return function(){
        console.log(\'something\');
        return new B();
    }
}

Answer 1

When you call the function without "new", what is it that you suspect "this" is pointing to? It'll be "window." Updating that is slower than updating the freshly-built new object you'll be using when you invoke it with "new".
