I have little confusion here please clear me out with these two points -

1. How we are getting baseProps as the whole object as props, i know we have passed the props while calling <FilteredList {//my props}/>, but how they are receiving/accessing in the baseProps ????
2. Now let believe once, any how we can get props here, but who is evoking that baseProps function as we can see that it was just normally returned. ????

Please clear me out with these points.
