JavaScript Interview Question:

How to use strings as array indexes using JavaScript?

Submitted by: Administrator

JavaScript does not have a true hashtable object, but through its wierdness, you can use the array as a hashtable.

<script type="text/javascript">
var days = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];

for(var i=0; i < days.length; i++) {
days[days[i]] = days[i];
}

document.write("days["Monday"]:"+days["Monday"]);
</script>

This produces
days["Monday"]:Monday
