Title case to sentence case?

[ahamelers]

I am looking for a package to intelligently transform sentences from title case to sentence case. I thought the title-case package would do it, but when I do this on a title cased string:

titleCase(string, {locale: 'en-US', sentenceCase: true})

It leaves the sentence exactly the same. Am I doing something wrong, or is this just not the package for me?

I think the 'titleCase' function changes to title case, not from.

The 'sentenceCase' function in the 'changeCase' package is the one you want.
