Assignment Operator

        let x = 10;
    let y = 5
     
    x += y; // artinya -> x = x + y;
    x -= y; // artinya -> x = x - y;
    x *= y; // artinya -> x = x * y;
    x /= y; // artinya -> x = x / y;
    x %= y; // artinya -> x = x % y;
     
    console.log(x);
    /*

    let y = 5
     
    x += y;
    // x=x+y
