Answer 5

r8w9 Michail Getmanskiy Do i need to place var or let before variable inside for loop? It work without it but what is correct?

Answer 7

IMHO: the variable x is a variable need that is only inside the for loop. To limit the scope of its existence and visibility only to the circle, I used 'Let' instead of 'Var'.

Answer 8

console.log("javascript is awesome!")
Why doesn't it post as text?
