Simple solution in Java using boolean

public static String kangaroo(int x1, int v1, int x2, int v2) {
        
        boolean canMeet = v2 < v1 && ((x2 -  x1) % (v1 - v2) == 0);
        
        return canMeet? "YES": "NO";
    }

C# solution:

string result = "NO";
    if (v1 <= v2)
    {
        return result;
    }
    if ((x2 - x1) % (v1 - v2) == 0)
    {
        result = "YES";
    }
    return result;

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";

}

Corner case, where: x1 = x2 and v1 = v2 ?

Answer: is "YES" the two congoroos meet after one jump at v1 = v2
