How to Sell Elixir AGAIN (2023)

Presented by Evadne Wu at Code BEAM Lite in Stockholm, Sweden on 12 May 2023

Synopsis

We have celebrated 10 years of Elixir and also nearly 25 years of Erlang since the open source release in December 1998.

Most of the libraries that were needed to make the ecosystem viable have been built, talks given, books written, conferences held and training sessions provided. A new generation of companies have been built on top of the Elixir / Erlang ecosystem. In all measures, we have achieved further reach and maturity than 5 years ago.

	When used on infinite streams such as the ones returned by `Stream.cycle/1`, the Stream
	Iterator will always return the next item.
