=={{header|Wren}}==

Well, we'll write a function for a bubble sort which we don't have in Wren-sort because it's normally much slower than the other methods. However, it's fast enough here.

<lang ecmascript>var bubbleSort = Fn.new { |s|

var chars = s.toList

var n = chars.count

while (true) {

var n2 = 0

for (i in 1...n) {

if (chars[i - 1].codePoints[0] > chars[i].codePoints[0]) {

chars.swap(i, i - 1)

n2 = i

}

}

n = n2

if (n == 0) break

}

return chars.join()

}

var s = "forever wren programming language"

s = bubbleSort.call(s).trimStart() // get rid of whitespace which will be at the front

</lang>

{{out}}
