Thanks Jazmin, this is the kind of thing I was looking for although I guess
in the end it is probably less readable than just assigning the variable at
the top, hmmm..
I guess you could do something like this:
x = defined?(x) ? x+="string" : ""
You can assign a value to a variable if it doesn't exist like this:
s ||= ""
but in your case you want to use the operand + so the string needs to exist.
Also an alternative for the loop example
regex = ''
10.times {
