I saw that line in some code
window.a = window.b = a;
How does it work?
Does the following always return true?
window.a == a
it means
window.b=a;
window.a=a;
OR You can say.
window.b=a;
window.a=window.b;
two assignments in a single statment
and
And one more thing
window.a==a right?
yes this is Right. It will return true
