Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs.

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

N − The nth value to return from the list.. Lst − The list of elements.. Return Value 2018-08-22 Erlang - list_to_binary - This method is used to convert an existing list to a list of binaries. List comprehensions are used to generate new lists from existing ones. The left side of `||` can be any expression. The right part, `X <- L` is called a generator, and it extracts each element from `L`, one by one. In addition to the generator, a list comprehension can also have one or more filters.

Erlang list

Using lists:foreach is a better solution - this is much faster than the list comprehension, and no need to nest the function. Erlang är ett generellt programspråk som från början (år 1987) utvecklades på forskningsavdelningen [2] [3] hos telebolaget Ericsson AB vid utvärderingen av olika programspråk för implementation av styrsystemen i telefonväxlar [4]. Takes a list of key-value tuples elements and builds a map. The associations can be in any order, and both keys and values in the association can be of any term. If the same key appears more than once, the latter (right-most) value is used and the previous values are ignored. Erlang - list_dir - This method is used to list down the contents of a particular directory. Calls Fun(Elem, AccIn) on successive elements A of List, starting with AccIn == Acc0.

In this post, I will briefly present the “theory” of lists and then present the Erlang’s lists module and its most important functions. List comprehensions (cont) The notation X <- L means "take one element from the list L". Since there are many elements in L, the expression in the left-hand side of the list comprehension is evaluated once for each element. Each value provides an element in the resulting list.
