Node Sass Utilities

node-sass-utils provides a collection of helper functions designed to simplify working with Sass values within JavaScript functions exposed to `node-sass` (and `dart-sass`, aka `sass` on npm). It addresses the complexity of handling Sass data types (like strings, numbers, booleans, lists, and maps) in a JavaScript environment. The library is currently at version 1.1.3. While its primary integration point was `node-sass`, it has been tested and confirmed to work with `dart-sass`, providing a bridge for utility functions regardless of the underlying Sass compiler implementation. This allows developers to write more robust and type-safe custom Sass functions in JavaScript. Key differentiators include methods for type assertion (`assertType`), type checking (`typeOf`, `isNull`, `isFalsy`), string manipulation (`sassString`, `unquote`), and crucial type casting utilities (`castToSass`, `castToJs`) for seamless data exchange between JavaScript and Sass. It is important to note its CommonJS module format and the specific initialization pattern requiring the Sass object.
