Why is this result?

Question

document.write(1&&2)==2

Answer 1

a&&b returns a if it it can be interpreted as false, and b otherwise. And any non-zero value is interpreted as true. So 1&&2 is evaluated as 2.

(You see Venkatesh's answer? This is why you should words instead of ==. People confuses that with actual code.)

Answer 2

My guess is this will lead to compilation error.

Because of braces placement. braces is only for a&&b and write will not return any values. So it will report an error
