associative array versus object in javascript
<p>In my script there is a need to create a hash table, i searched in google for this. Most of the folks are recommending JavaScript object for this purpose. Problem is, some of the keys in the hash table have "." in them. I am able to create these keys easily with the associative arrays.</p>

<p>I don't understand why associative arrays are bad. First thing that is mentioned in the sites that i looked at is the length property. I am coming from the Perl background, where i used hashes. Most common uses were to get the value from a key, check if a key exists, delete a key-value pair, add a key-value pair. If these are my common uses, can i safely use associative array? </p>
