? true : false is redundant here.
The strict equality operator (===) checks whether its two operands are equal, returning a Boolean result.
And in our case, if two conditions are true, Logical AND (&&) will return true, otherwise false

what if we have two numbers with the same length but a < b. For example 13 and 25. the output will be 251325, but 132513 is needed

if TEST is passed, BUT....
if ATTEMPT this solution is:

SyntaxError: Invalid regular expression: /:-($/: Unterminated group

at String.match ()

Ternary for the win!

'$' is end of line in Regex

why is the +"$" needed?

I did the same thing, but I wish I knew what the '[object Array]' part meant

answered already for another solution

Hi MehLON, Could you explain me how +value works?, I didn't see it before. :)

Wow, your solution is awesome. Thanks a lot.
