Function firstUniqueChar (str ){
Var str = str | "",
I = 0,
K = "",
_ Char = "",
CharMap = {},
Result = {name: "", index: str. length };
For (I = 0; I _ Char = str. charAt (I );
If (charMap [_ char]! = Undefined ){
CharMap [_ char] =-1;
} Else {
CharMap [_ char] = I;
}
}
For (k in charMap ){
If (charMap [k] <0 ){
Continue;
}
If (result. index> charMap [k]) {
Result. index = charMap [k];
Result. name = k;
}
}
Return result. name;
}
