Why does the following code outputs 6? [JS]

Question

function addRek( x ) {
if( x == 0 ) {
return 0;
} else {
return x + addRek( x - 1 );
}
}

console.log( addRek(3) );

Thank you. :).

Answer 1

This program recursively calls addRek till your passed value isn't reduced to zero.
so output is
3+2+1=6

Answer 2

Sorry for my explanation but does it really outputs 6

Answer 3
