## Overview

The **`join()` method** of the `Enum` module is used to join the given enumerable to a string with a separator.


## Syntax

```
Enum.join(enumerable, joiner \\ "")
```

## Parameters

- `enumerable`: The enumerable/list of strings.
- `joiner`: The separator string used for joining the strings.

## Return value

The method returns a string.

## Code

lst = ["hello", "educative", "answers"]
joiner = " -- "
joined_string = Enum.join(lst, joiner)
IO.inspect lst
IO.puts "separator: #{joiner}"
IO.puts "--------"
IO.puts "Joined string from the list -"
IO.puts joined_string


## Explanation

- **Line 3:** We join the list of strings into a string based on the given separator using the `Enum.join()` method.
- **Line 8:** We print the string returned after the join.
