ternary operation in js

Question

Maybe I do not understand ternary operation but

if I am right it's

    test ? true : false

So this should give

function toto(x, y)
{ 
    return (x > 0 ? x < 7 ? true : false : false &&
                y > 0 ? y < 6 ? true : false : false)
}

true only if 0

but if I do

toto(4,6)

it returns true, why? What am I missing ?

Answer 1

just do like this :

function toto(x, y)
{ 
    return (x > 0 ? x < 7 ? true : false : false ) &&
                ( y > 0 ? y < 6 ? true : false : false)
}

with the bracket before and after the exp1 and exp2 and yes it's a bit unreadable ^^

edit : I also would do

return (x > 0 && x < 7) && (y > 0 && y < 6)
