Question

Is it necessary to assign a valuse to a variable? or

i can just create a global variable and use it inside a loop without assigning it anything?

'''
var x; // Declared a variable
'''

undefined can be used inside a loop?

You can do it like that, yes. I'd highly recommend to look into array functions instead of regular for loops though
