What do you thing this function does? Excuse the imperfect usage of value destruction.
function encodeLocationCoords(value: {x: number, y: number, z: number}): string {
return [value.x, value.y, value.z].map(toString).join(COORD_NUM_SEP);
}
If you thought that it just encodes the numbers into a string separated by COORD_NUM_SEP then I am sorry.
What you get is '[object Undefined]_[object Undefined]_[object Undefined]'.
Because why would typescript linter or compiler tell you that toString is
not a string (as join expects)?
The more I use Typescript, the less I think it makes Javascript "bearable".
In Haskell, you're allowed to do that. Other features of truly "functinoal"
languages I miss are for example Enums with attached data or newtype thing without creating empty classes - wordy and visually just weird...
