@fzaninotto @djhi
I'm not sure why I'm getting an empty string here, but I get an error here ((intermediate value)(intermediate value)(intermediate value).map is not a function)

const value = ""
Array.isArray(value || []) ? value : [value]
// ''

Nullish coalescing seems to fix this particular case, though I'm not sure of any caveats.

const value = ""
Array.isArray(value ?? []) ? value : [value]
// [ '' ]

Good catch

.map(item =>
choices.find(
choice => String(item) === String(get(choice, optionValue))
