Edit: this seem to be enough

if (!JsNumber.isSafeInteger(value)) {
  throw IllegalArgumentException("Invalid number: $value")
}

Given an exported function like

fun writeInt(value: Int)

And being that in JS (or even TS) there is no guarantee the submitted number is indeed an integer , what's the best path to take to ensure data correctness?

Which type do you have at start?

[Edoardo Luppi]

@turansky that's the issue, it's submitted externally and in TypeScript it's only number, so a user can submit any kind.
But that check works perfectly for my needs.

You can use Number.toInt() + check
