Erlang Programming Language

Erlang is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.

#What is Erlang?

Erlang is a functional programming language created for telecommunications applications that require high availability, fault tolerance, and distributed computing. Erlang uses message-passing concurrency, and its design allows for hot-swapping of code to minimize downtime.

#Erlang Key Features

Some of the most recognizable features of Erlang include:

  • Process-oriented programming model that uses lightweight processes to run concurrent and distributed computations
  • Built-in support for fault-tolerance and error-handling, including the ability to recover from system failures without shutting down the entire system
  • The ability to perform live code upgrades and downgrades without stopping the system
  • Built-in support for distributed computing and networking
  • Dynamic typing and pattern matching
  • A rich set of built-in libraries for networking, file I/O, and database access

#Erlang Use-Cases

Some common use cases for Erlang include:

  • Developing high-availability and fault-tolerant telecommunication systems such as telephony switches, voice mail, and messaging systems
  • Building scalable web applications that require real-time updates and messaging, such as chat applications and massively multiplayer online games
  • Developing high-performance, distributed systems such as database management systems, web servers, and cloud computing platforms

#Erlang Pros

Some of the most known pros of Erlang include:

  • High fault-tolerance and reliability, making it suitable for building critical systems that require continuous availability
  • Built-in support for concurrency, message-passing, and distributed computing
  • Good performance in handling large numbers of lightweight processes

#Erlang Cons

Some of the most known cons of Erlang include:

  • Limited availability of third-party libraries and tools compared to other programming languages
  • A steep learning curve due to its unique syntax and functional programming concepts
  • Limited support for object-oriented programming compared to other programming languages

#Erlang Summary

Erlang is a functional programming language designed for building highly available and fault-tolerant distributed systems with built-in support for concurrency and message-passing.
