check if a number is odd or even

const oddOrEven = (int) => {
    if (typeof int == "string" && int) {
        if (parseInt(int) % 2) return "Odd"
        else return "Even"
    } else if (typeof int == "number") {
        if (int % 2) return "Odd"
        else return "Even"
    } else return undefined
}

// example
// code | expected output

oddOrEven(0)   // Even
oddOrEven(10)  // Even
oddOrEven("0") // Even
oddOrEven("10")// Even
               //
oddOrEven(1)   // Odd
oddOrEven(11)  // Odd
oddOrEven("1") // Odd
oddOrEven("11")// Odd
