If the "name" property of "a" comes before the "name" property of "b" in alphabetical order, then the function returns -1, which means "a" should come before "b" in the sorted array. Otherwise, if the "name" property of "a" comes after the "name" property of "b" in alphabetical order, then the function returns 1, which means "b" should come before "a" in the sorted array.
