I don't understand how lists:map function is used here. Could someone please explain? % perform M runs with N calls to F in each run. % For each of the M runs, determine the average time per call. % Return, the average and standard deviation of these M results. Combines the operations of map/2 and foldl/3 into one pass. Example: Summing the elements in a list and double them at the same time: > lists:mapfoldl(fun(X, Sum) Thus erlang:hibernate/3 never returns to its caller.

Maps are considered experimental during OTP 17 and may be subject to change. The documentation below describes it being possible to use arbitrary expressions or variables as keys, this is NOT implemented in the current version of Erlang/OTP.

This structure is a finite mapping from keys to values with a flat internal representation: a map is essentially two arrays: one of Detailed introduction of mapping group Map in Erlang Time：2019-3-17 The main problem is Map matching, so by the way, recall the mapping group Map in Erlang, which is called Hash hash or Dict dictionary in other languages. Erlang supports mapping groups from version R17 Erlang - from_list - This method is used to generate a map from a list. Programming Erlang, 2nd Ed was written before maps were introduced in release 17 (as experimental feature) and it seems that author of book, Joe Armstrong was too optimistic about them. Still some of proposed functionality and syntax is not yet implemented (or never will be).
