#For Loops

##for A for loop, as mentioned above, is useful for looping with a given number of iterations. Use it when you want to do something x times, such as changing the values in an array or counting the number of vowels in a string.

The common and fundamental syntax for a for loop in JavaScript is as follows:

for (var i = 0; i < n; i++) {
  // block of code
}

#puts vs. print vs. p ###The 'puts' (short for "put string") and 'print' commands are both used to display the results of evaluating Ruby code. ###Both 'puts' and 'print' call the 'to_s' method on the object AND return nil.

###The primary difference between them is that 'puts' adds a newline after executing, and 'print' does not. ###They don't RETURN anything so the RETURN value is nil. ###Using 'p' calls the 'inspect' method on the object.

print "Milan"
Milan => nil
