# Question about StringJoin and Join [closed]

Consider

Join[Range[3], {Range[3]}]


{1, 2, 3, {1, 2, 3}}

and

StringJoin["abc", {"abc"}]


"abcabc"

Both expressions contain a list and a nested list, but the results are different. Why?

If this question can be reworded to fit the rules in the help center, please edit the question.

• Because those are different functions. "All lists are ignored:" - second example in StringJoin. – Kuba Aug 12 '16 at 12:02
• You ask "Why?" Because Wolfram Research, Inc., did it that way. If you have a beef about it, take it up with WRI. – m_goldberg Aug 12 '16 at 13:03
• the alternative would be to throw an error, i suppose that's good enough reason. – george2079 Aug 12 '16 at 18:46
