Is Erlang interpreted or compiled?
No. Normally Erlang code is compiled ahead of time into BEAM bytecode. Depending on whether Erlang was started in embedded or interactive mode, the modules are either loaded on startup, or dynamically as they are referenced. If you are building a release, you basically have to compile ahead of time.
What type of programming language is Erlang?
Erlang (/ˈɜːrlæŋ/ UR-lang) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.
What is Erlang language used for?
Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging.
What is difference between compiled and interpreted language?
A compiled language is a programming language whose implementations are typically compilers and not interpreters. An interpreted language is a programming language whose implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions.
Which coding language is used in WhatsApp?
Erlang
WhatsApp is based on Erlang, a programming language designed for scalable systems with real-time high availability requirements.
Which apps use Erlang?
Messaging apps, including some famous examples like WeChat and WhatsApp, use Erlang to handle insane amounts of concurrent users. Erlang has a wonderful messaging platform called ejabberd that can be used to create large-scale chat apps. Message queue systems.
Why WhatsApp is written in 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.
Which is a feature of the Erlang programming language?
The Erlang programming language has immutable data, pattern matching, and functional programming. The sequential subset of the Erlang language supports eager evaluation, single assignment, and dynamic typing. A normal Erlang application is built out of hundreds of small Erlang processes.
Is the Erlang VM a compiled or opcode format?
Erlang is a compiled language – most modern production systems compile with the HiPE compiler which generates object code. Where people get confused is that the Erlang VM has its own code loader and binary file format, so they tend to think that BEAM is always an opcode-type format (which it can be).
Can a programming language be inerpreted and compiled?
First of all, a programming language can be both inerpreted and compiled. Interpretion and compilation are just methods of generating executable code from the source code. With an interpreter the source code is being read and interpreted by an interpreter which then executes the code as it interprets it.
How is hot swapping used in the Erlang language?
Hot swapping, where code can be changed without stopping a system. The Erlang programming language has immutable data, pattern matching, and functional programming. The sequential subset of the Erlang language supports eager evaluation, single assignment, and dynamic typing .
