Is there a dictionary implementation in JavaScript?

Question

How can I implement an array with an indexer in JavaScript? Is there something like a dictionary in .Net?

Answer 1

var nDictionary = Object.create(null);

function setDictionary(index, value) {
    nDictionary[index] = value;
}

function getDictionary(index) {
    return nDictionary[index];
}

setDictionary(81403, "test 1");
setDictionary(81404, "test 2");
setDictionary(81405, "test 3");
setDictionary(81406, "test 4");
setDictionary(81407, "test 5");

alert(getDictionary(81403));
