/*
write a function called jumpingJack that takes a name as a parameter,
and logs out "<name> jumped over the hill"$

write a function called areYouRich that takes a dollar amount as  a parameter,
. IF that dollar amount is below 100, prints "You're poor!", if the amount
is between 100 and 100000, prints "Youre doing pretty good", and if the amount
is more thatn 100000, prints "you're rich!"$

create an object for an airplane type, give it properties and a method
called fire guns that prints "<airplane name> is shooting its guns"$

ex: 
var plane = {
    type: "spitfire",
    propellers: 2
}


create a list of russian cities that were captured by the germans in ww2
use a for loop to print out "the germans captures the city of <city name> during ww2"
