title: How to save prompt input into array
body: <p>I`m having some issue with Javascript.
  We just started to study it a couple weeks ago and I have to do a work for class:</p>
  
  <p>Need to do a prompt. get 10 numbers input (10 grades) from the user.
  put the numbers into an array and then do some functions with it.</p>
  
  <p>My question is how do I save the input in the array?
  We learned about all the loops already. Tried to search online but didn`t found an answer.</p>
  
  <p>I would love if somebody could explain how I do it.
  Thank you very much.</p>
