alert(x[x[x.length%2]]);
//answer is:3.
//but how do i read this?
//i would first read the modulo, result =1;
//then i dont know what kind of x i should take of this array. and where is the „3“ resulting from? 😫

Answer 1

Youre welcome ^_^

Answer 2

3 comes from the x array

Answer 3

so
x.length%2 = 1
that makes it x[x[1]]
x[1] is 2
that makes it x[2]
and x[2] is 3
