    Simple Mathematical Solution in JavaScript

    

    function kangaroo(x1, v1, x2, v2) {
    // Write your code here
    // Solve for t: x1 + d1 * t = x2 + d2 * t
    let t = (x2 - x1) / (v1 - v2);

    // If t is negative, they never meet in forward time
    if (t < 0 || !Number.isInteger(t)) {
        return "NO";
    }

    return "YES";

}
