Algorithm for joining e.g. an array of strings

Question

I have wondered for some time, what a nice, clean solution for joining an array of strings might look like. Example: I have [\"Alpha\", \"Beta\", \"Gamma\"] and want to join

Answer 1

Most languages nowadays - e.g. perl (mention by Jon Ericson), php, javascript - have a join() function or method, and this is by far the most elegant solution. Less code is better code.

In response to Mendelt Siebenga, if you do require a hand-rolled solution, I'd go with the ternary operator for something like:

separator = ","
foreach (item in stringCollection)
{
    concatenatedString += concatenatedString ? separator + item : item
}
