Who will help me understand this...

Question

var x=1,y=1;
document.write(++x==2 && y++ ==1);
document.write(x,y);
X=2,y=2

var x=1,y=1;
document.write(++x==3 && y++ ==1);
document.write(x,y);

X=2,y=1

Answer 1

what could surprise you is the last document.write:

as ++x is not equals to 3, second part of condition is not executed, so y is no increased ;)

Answer 2

++x means increment the value of x first and use it so in the first print statement x = 2 now so it would look like this 2==2&&

y++ means use the current value of y first and then increment so in the print statement y = 1 and once the statment has finished y increases to 2

So y and x both equal 2 after the first print method but inside the method it would look like this (2==2&&1==1);

Answer 3

Hi! do you not understand the entire code or some part of it?
