Only Safari browser actually supports tail optimization, so it is better to think that JS does not support it at all.

JS does support tail call optimization. This solution however is not tail recursive, so will eventually cause a stack overflow if n is sufficiently large.

Thank you.
I'm not familiar enough with JS to confirm if this is good practice, in the sense that :

• does JS support tail optimization ?
• If so, does this particular construct allows it.

nice
