  1. the "listHTML" variable is holding a string that is being constructed in several operations
  2. the "print" function just puts the string argument onto the page
  3. the "+=" is a concatenating assignment, basically it means "add this onto the end"

only thing m still confused about is passing "list" as an argument to the function "printList" and then in for loop we using length property to check the no of items in that. but where is "list" to check the length property for it? is this an imaginary list for as many as no of items in the list?
