+Calling one of the [Ember `String` methods](https://api.emberjs.com/ember/3.22/classes/String) (camelize, capitalize, classify, dasherize, decamelize, htmlSafe, underscore) directly on a string is deprecated.
 
 While Ember addons (`ember addon …`) have prototype extensions disabled by default, they are enabled for applications (`ember new …`) making you able to call `"Tomster".dasherize()`, for example.
 Instead of calling the method on the string, you should instead import the function from `@ember/string`.
