You will want to use the #join(separator) method.
See the official ruby docs for Array#join
Example:
['h', 'e', 'l', 'l', 'o'].join('')
=> "hello"
A good place to start learning the basics of Ruby is at Code Academy.
I also recommend dash for browsing documentation offline!

You can just calljoin, the empty string argument isn't needed.

Nov 14 '18 at 8:42
@Stefan is right and it should be called without an argument when an array is being joined without a separator

y.join()
=> "is"
z.join()
=> "sunday"
Then do this:
x.join + y.join + z.join()
=> "todayissunday"
Or combine x, y, z into one array and call join on it, like this:
Array(x + y + z).join
=> "todayissunday"

You can use the .join() method like this:

z = ["s", "u", "n", "d", "a", "y"]
x.join()
=> "today"
y.join()
=> "is"
z.join()
=> "sunday"
Then do this:
x.join + y.join + z.join()
=> "todayissunday"
Or combine x, y, z into one array and call join on it, like this:
Array(x + y + z).join
=> "todayissunday"
