It seems that Erlang introduced maps in version R17A. But, if I go to downloads I only see version 17.5, there's no version R17A.. So, is it released and stable yet? Does the latest stable Erlang has Map support?

The associations may be in any order and both keys and values in the association may be of any term. The maps implementation that came with Erlang 17.x and 18.0 is complete, but only within the confines of the maps module. The major differences come from the syntax. Only a minimal subset of it is available: literal map declarations (# {}, # {key1 => val1, "key2" => val2}) A map Mconsists of a number of associationsand keeps an association Any term, compound or otherwise, is a viable key or value. are recognized by guard tests erlang:is_map/1.

Calls Fun(Elem, AccIn) on successive elements A of List, starting with AccIn == Acc0. Fun/2 must return a new accumulator, which is passed to the next call. The function returns the final value of the accumulator. Acc0 is returned if the list is empty.. Example: > lists:foldl(fun(X, Sum) -> X + Sum end, 0, [1,2,3,4,5]). 15 > lists:foldl(fun(X, Prod) -> X * Prod end, 1, [1,2,3,4,5]). 120

D Elixir Erlang F# Fortran Go Haskell Java Javascript Kotlin Lua MySql Node. aliasing C++ entities from Lua Permissions system Load Goldsrc maps Sep  Returns a map iterator Iterator that can be used by maps:next/1 to traverse the key-value associations in a map. When iterating over a map, the memory usage is guaranteed to be bounded no matter the size of the map.

Specifically, we will make it run on multiple Erlang nodes, balance the load between them, and begin to make the code fault-tolerant.

EEP 43: Maps Abstract. The journey of Maps and this EEP has been long and by no means a straight-forward and continuous one. I had a crystal clear picture of what I wanted Maps to be when we first started discussing it within OTP about two-three years ago.

When iterating over a map, the memory usage is guaranteed to be bounded no matter the size of the map. The call fails with a {badmap,Map} exception if Map is not a map. Example: 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.. Exceptions returns badarg instead of badmap, this will change in the future releases.
