Join strings

[Fresh Mix]

What is the simples way to join strings?

tmp1 = 'aa'
tmp2 = 'bb'
tmp3 = nil
tmp4 = nil
tmp5 = 'dd'

result = 'aabbcc'

 

[Leo]

result = 'aabbcc'

local_variables.select {|v| v != '_'}.map {|v| eval(v)}.join
=> "aabbdd"

Unfortunately, I don't know where you got the "cc" from in your
example.

[tmp1, tmp2, tmp3, tmp4, tmp5].join

The problem & answer is almost the same as those to your question from
about a month ago:
