Script Preparation code:

var intMap = new Map();
for(i=0; i < 1000; i++){
  intMap.set(i, "a" + i);
}

var stringMap = new Map();
for(i=0; i < 1000; i++){
  intMap.set(i.toString(), "a" + i);
}

Tests:

String
for(i=0; i < 1000; i++){ var a = stringMap.get(i.toString()); }
Int
for(i=0; i < 1000; i++){ var a = stringMap.get(i); }
