I am trying to convert a string array to a number array A quick google search have lead me to this solution.

    let numbersAsStringArray = originalQueryParams[property] ?? []
    let numbers = numbersAsStringArray.map((i) => Number(i));

where I keep getting this i

Property 'map' does not exist on type 'string | string[]'.

numbersAsStringArray is just an simple array with a number in as a string.
