Could anyone help me to understand the logic / process happening behind the scenes ? Thanks in advance.

Question

What is the output of this code ?
var a = 10;
var b = 11;
var c;

if (!(a++ >= 10 || b++ >= 11)) {
c = a + b;
alert(a + "" + c);
} else {
alert(a + "" + b);
}
}

Answer 1

a++ >= 10 happens like
=> 10>=10 and a=a+1
=>true, a=11
so if (! (true || b++>=11))
=> If (! (true))
=> If false
So Then else part get executed..
alert(a + "" + b)
=> 11 11
