println()
# Julia requires () like Python 3 and has a printing function
# print with no linefeed or println including a line feed.
# Note that println is a function so it needs the ()
Hello World
# And then a conditional test

if variable_named_bob < 900

end
# notice no colons or brackets required but instead we have an end
# also you can use a ; instead of a new line and Julia really
# isn't worried about indentation or extra spaces so I could have
# written this instead
if variable_named_bob < 900
println ( "Hello World 2" ) ; end
# You can also use the ternary operator
variable_named_bob < 900 ? println("Hello World 3") : nothing
# and you can use short circuit evaluation
variable_named_bob < 900 && println("Hello World 4")
Hello World Hello World 2 Hello World 3 Hello World 4
