Understanding a Useful Elixir String Split Trick

The author describes a scenario where you might encounter a string with two delimiters and want to extract the text within those delimiters. Ordinarily, splitting a string by multiple delimiters could be cumbersome, but Elixir's `String.split/2` offers a neat solution. Instead of splitting by a single pattern, you can provide a list of strings to split on, allowing for more complex splitting behavior. For example, to extract the word 'hello' from the string "{hello}", you can use `String.split/2` with both '{' and '}' as delimiters, followed by `Enum.at/2` to get the enclosed text. The provided Elixir Interactive Shell (IEx) example demonstrates this functionality succinctly.
