ruby array pack and unpack functionality in javascript?

Question

What are the Javascript functions or libraries that are equivalent to Ruby's pack and unpack functions for the Array class? I'm particularly interested in converting hex strings to strings.

irb(main):022:0> ["446f67"].pack("H*") => "Dog"

I'm not a javascript programmer and would rather not roll my own converter if libraries are available.

I don't think JavaScript has a function that does quite the same thing; pack seems to be a Ruby specific. If you're using pack to turn an object into a string, which can be sent over a network, you could use JSON instead. The Prototype library provides methods for turning objects into JSON-encoded strings. There are also Ruby libraries for working with JSON (encoding and decoding) such as:
