Why “do…while” does not exist in F#

Question

I cannot find \"do...while...\"

I have to code like this:

let bubbleSort a=
    let n = Array.length a
    let mutable swapped = true
    let mutable i =         


        

Answer 1

break and continue would be a really useful feature additions; they're reserved words, and maybe we'll see them in a future version of the language. The lack of them is an occasional minor annoyance, but hardly makes the language 'unsuitable'. In the mean time, a mutable sentinel works, as you have in your example.
