why the result is 8??

Question

var a = 6;
var b = 3;
b--;
document.write(a+b);

Answer 1

because b--; change the value of b from 3 to 2... remember: "b--;" is the same as if you typed "b=b-1;"... when you get to the next line, a+b is equal to 6+2 which gives you 8 as a result.

Answer 2

var a = 6;
var b = 3;
b--; // b become 2 after this line
document.write(a+b); // 6 + 2
