Implementing "Did you mean ...?" functionality in Elixir using Jaro Distance

The article provides a comprehensive guide on how to implement a 'Did you mean ...?' feature in Elixir to enhance user experience by suggesting corrections for incorrect input. It explains the use of the Jaro Distance metric, a measure of similarity between two strings, in identifying approximate matches. The tutorial includes creating an Elixir module `JaroValidator` that validates keys against a list of accepted keys and suggests the closest valid alternatives if an invalid key is found. The key points covered include the implementation of a `validate/2` function that iterates over the keys in a data map, checks for validity, and generates suggestions using the `jaro_suggestions/2` function.
