How to write a JS function to check if a number is odd or even or invalid? (fractions are neither odd nor even)

The input comes as a single number argument.

Examples:

Input: 5

Output: odd


Input: 8

Output: even


Input: 1.5

Output: invalid

The output should be printed to the console.

Print odd for odd numbers, even for even number and invalid for numbers that contain decimal fractions.

My JS function:

function evenOdd(number) {
    let reminder = number % 2;
    if (reminder == 0) {
        console.log("even");
    } else if (reminder == Math.round(reminder)) {
        console.log("odd");
    } else {
        console.log("invalid");
    }
}
 
evenOdd(0);
