Help can someone explain the line in var z in this code? I get confused. Thanks

Question

What is the output of this code
var a = 3;
var b = 2;
var z = (++b+a--)%5;
document.write (z);

Answer 1

(++b+a--) results in 6 The ++b happens first which makes b equal to 3. Then b+a happens (3+3). The result of this is then used for the modulus 6%5 and z is set to 1. Then the -- of a sets a to 2.

Answer 2

z = (3 + 3)%5
z= 1

here in z ++b means that first increase b and than add and a-- means first add a and decrease the value of a .

now value of a is 2 and value of b is 3.
