Why is Erlang so popular?
Erlang is perfectly suited to the distributed nature of modern computing and today’s multicore CPUs. Erlang processes allow us to easily scale systems, both by adding more machines and by adding more cores to existing machines. Reliability. Erlang has a motto – “let it crash”.
Is Erlang still relevant?
Erlang’s popularity has been declining in the last five years. While there are spikes of interest in Erlang, its overall trajectory is on a downward trend. In terms of purely functional languages, Erlang’s downward trajectory is somewhat normal, with Haskell also in decline.
Does Ericsson still use Erlang?
Ericsson uses Erlang to develop many of its products and an estimated 40 percent of all mobile traffic worldwide is carried over the company’s network solutions. Erlang is suitable for any application that requires a robust server solution and it is portable for most operating systems and processor architectures.
Why did WhatsApp choose Erlang?
In using Erlang, WhatsApp is part of a larger push towards programming languages that are designed for concurrency, where many processes run at the same time. As internet services reach more people—and juggle more tasks from all those people—such languages become more attractive.
Why was Erlang created?
Erlang was designed with the aim of improving the development of telephony applications. The initial version of Erlang was implemented in Prolog and was influenced by the programming language PLEX used in earlier Ericsson exchanges.
Why is Erlang so fast?
In the usual case, Erlang does not use a contiguous chunk of memory to represent a sequence of bytes. The result is that concatenating two strings (I/O lists) takes O(1) time in Erlang, compared O(N) time in other languages. This is why template rendering in Ruby, Python, etc. is slow, but very fast in Erlang.
Why is Erlang so reliable?
So here’s a recap of what the Erlang VM gives us in pursuit of reliability: Lightweight, shared-nothing processes that communicate via asynchronous messages. A built-in mechanism for processes to react to failures in other processes.
Why is Erlang reliable?

Why is Erlang slow?
Erlang is slow, if your problem has a certain structure. Your problem must be CPU bound. And constant factors must matter. In almost all other cases it is more capable than most other systems.
What is Erlang programming language?
Erlang is a twenty-five-year-old programming language that has yet to win a popularity contest, and almost certainly will never win any medals for speed, let alone any tiaras for syntactic beauty. The language is slow, awkward, and ugly. Refactoring Erlang code is a pain.
Is Erlang faster than Ruby?
For the programmer who wishes to write fast programs using Erlang — the sorts of programs that start, run, write some output, and exit — there is hope on several fronts. A native-code compiler is available, and according to numerical benchmarks, it makes Erlang programs faster than Ruby]
Why does concatenation take so much time in Erlang?
The result is that concatenating two strings (I/O lists) takes O (1) time in Erlang, compared O (N) time in other languages. This is why template rendering in Ruby, Python, etc. is slow, but very fast in Erlang.
How does refactoring work in Erlang?
In Erlang, each function is passed all the information it needs, and you get a compiler warning if it was passed any information it doesn’t need. In some sense, refactoring is integrated into development; it is not a distinct activity requiring bountiful test coverage and several pots of coffee.
