Ever wanted to convert snake case to camel case? You can use Macro module for that. Except it should not be used this way. As it states itself:

Do not use it as a general mechanism for underscoring or camelizing strings as it does not support Unicode or characters that are not valid in Elixir identifiers.

But with recase it is easy and reliable: Recase.to_camel(“some_value”) # => “someValue”

recase also supports: UpperCase, kebab-case, Path/case, CONSTANT_CASE, and dot.case
