JS: difference between associative arrays and objects?

Question

I learned about objects before I got to know associative arrays. Both seem to work with the key:value concept but I don't really understand the difference between them.
plz help a noob out

Answer 1

In JavaScript, associative arrays and objects are the same thing. Every object is internally much like a hash table with any number of keys and corresponding values.
