Erlang - Lists
The List is a structure used to store a collection of data items. In Erlang, Lists are created by enclosing the values in square brackets.
Following is a simple example of creating a list of numbers in Erlang.
-module(helloworld). -export([start/0]). start() -> Lst1 = [1,2,3], io:fwrite("~w~n",[Lst1]).
The output of the above example will be −
[1 2 3]
