Arc vs Erlang: What are the differences?
Developers describe Arc as "A dialect of the Lisp programming language developed by Paul Graham and Robert Morris". Arc is designed for exploratory programming: the kind where you decide what to write by writing it. A good medium for exploratory programming is one that makes programs brief and malleable, so that's what we've aimed for. This is a medium for sketching software. On the other hand, Erlang is detailed as "A programming language used to build massively scalable soft real-time systems with requirements on high availability". Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems.
Arc and Erlang can be primarily classified as "Languages" tools.
Erlang is an open source tool with 7.74K GitHub stars and 2.1K GitHub forks. Here's a link to Erlang's open source repository on GitHub.
AdRoll, Grooveshark, and Heroku are some of the popular companies that use Erlang, whereas Arc is used by Helpful, Cask, and Icalia Labs. Erlang has a broader approval, being mentioned in 70 company stacks & 47 developers stacks; compared to Arc, which is listed in 7 company stacks and 6 developer stacks.
