I think I am missing something (thank you in advance for your
patience)
My Attempt:
<script>
var ara1 = ['a','b','c','d','e'];
var ara2 = ['c','e'];
function ArraySubtract(ara1,ara2) {
var aRes = new Array() ;
for(var i=0;i<ara1.length;i++) {
if( ! (ara2.contains(ara1[i]) )) {
aRes.push(ara1[i]) ;
}
}
return aRes ;
}
wikify(ara1+' (ara1)'+'\n' ,place);
wikify(ara2+' (ara2)' +'\n' ,place);
wikify(aRes+' (aRes)' +'\n' ,place);
</script>
Results: (wikify x3 to separate results / error)
a,b,c,d,e (ara1)
c,e (ara2)
ReferenceError: aRes is not defined
Did I miss something? / Wrong usage?
Mike
