In Elixir, to perform a join on tuples, you can use the Tuple.join/2 function. This function takes two tuples as arguments and joins them together into a single tuple. For example, if you have two tuples tuple1 = {:a, :b} and tuple2 = {:c, :d}, you can join them like this: Tuple.join(tuple1, tuple2), which would result in {:a, :b, :c, :d}.

To create a directory with a specific name in Elixir, you can use the File.mkdir/1 function. This function takes a string representing the directory name as an argument and creates a directory with that name in the current working directory. Here's an example of how you can create a directory named "my_directory": File.mkdir("my_directory") This code will create a directory called "my_directory" in the current working directory.

In Elixir, "?\s" is a way to represent the whitespace character in the form of a single character literal. The question mark followed by a backslash and a specific character inside the single quotes represents that character's ASCII value. In this case, "?\s" represents the whitespace character.What is a macro in Elixir?In Elixir, a macro is a piece of code that operates on other code at compile time.

To concatenate lists from map properties in Elixir, you can use the Map.get function to access the list values from the map and then use the ++ operator to concatenate them. Alternatively, you can use the | operator to concatenate lists directly without explicitly accessing the map properties. It is important to handle cases where the map property may not exist or may not contain a list to avoid errors.How to concatenate lists in Elixir.

To convert a bitstring into a string in Elixir, you can use the to_string/1 function. This function converts a binary to a UTF-8 encoded string. You can simply pass the bitstring as an argument to the to_string/1 function, and it will return the corresponding string representation. For example: bitstring = <<104, 101, 108, 108, 111>> string = to_string(bitstring) IO.

To get the size of arbitrary data in bytes in Elixir, you can use the byte_size/1 function. This function takes a binary as an argument and returns the number of bytes in that binary. For example, if you have a string "Hello, World!", you can get its size in bytes like this: data = "Hello, World!" size_in_bytes = byte_size(data) IO.puts(size_in_bytes) This will output 13, as the string "Hello, World!" contains 13 characters, each taking up one byte.

To get a datetime list using stream in Elixir, you can use the Stream module along with functions like Stream.iterate and Timex.You can create a stream of datetime values by using Stream.iterate function to generate a sequence of date-time values starting from a given initial date-time. Then, you can use Timex library to manipulate and format the date-time values as needed.Here's an example code snippet that demonstrates how to generate a stream of datetime values: start_datetime = Timex.

To update an entry inside a nested map in Elixir, you can use the Map.update function. First, you need to access the nested map using the appropriate keys. Then, you can use Map.update to update a specific key inside the nested map. For example, if you have a nested map nested_map and you want to update the value of key :inner_key inside the nested map stored under :outer_key, you can do so by using the following code: updated_nested_map = Map.

In Elixir, you can convert map entries into a list of pairs using the Map.to_list/1 function. This function takes a map as an argument and returns a list of key-value pairs. Each pair is represented as a tuple where the first element is the key and the second element is the corresponding value. This allows you to iterate over the map entries using functions like Enum.each/2 or Enum.map/2.

In Elixir, one way to get duplicates in a list is to use the Enum.group_by function to group duplicate elements together, and then filter out groups with a count of 1. Another approach is to iterate over the list and keep track of elements that have already been seen, adding them to a separate list if they appear again. Both methods can help identify and extract duplicates from a given list in Elixir.What is the expected behavior when duplicate elements are encountered in a list in elixir.
