Erlang

Erlang is a general-purpose language originally created to develop telecom applications but that’s now used as a way to build concurrent applications. With this highly-scalable, functional language you can create telecom tools, web apps, distributed computing, and any other solution that requires handling multiple simultaneous inputs.

Joseph Leslie Armstrong (27 December 1950 – 20 April 2019) was a computer scientist working in the area of fault-tolerant distributed systems. He is best known as one of the co-designers of the Erlang programming language.
