Erlang Language Loop and Recursion Anonymous function
Example
Here 2 examples of recursive anonymous functions based on previous example. Firstly, simple infinite loop:
InfiniteLoop = fun
R() ->
R() end.
Secondly, anonymous function doing loop over list:
LoopOverList = fun
R([]) -> ok;
R([H|T]) ->
R(T) end.
These two functions could be rewritten as:
InfiniteLoop = fun loop/0.
In this case, loop/0 is a reference to loop/0 from remarks. Secondly, with little more complex:
LoopOverLlist = fun loop/2.
Here, loop/2 is a reference to loop/2 from list example. These two notations are syntactic sugar.
