destructuring assignment typescript error

I have a function getMoveLocation that return array [col, row]. Then I want to use it like this

const [lastCol, lastRow] = getMoveLocation(lastSquares, squares)

const [lastCol, lastRow] = getMoveLocation(lastSquares, squares)

But typescript yells at me

Type 'number[] | undefined' must have a '[Symbol.iterator]()' method that returns an iterator.

Type 'number[] | undefined' must have a '[Symbol.iterator]()' method that returns an iterator.

Anyone maybe know solution?
