xmldom/is-dom-node

@xmldom/is-dom-node is a TypeScript library that provides utility functions for checking and asserting various types of DOM nodes, particularly useful when working with XML in NodeJS or browser environments. It offers both `is...` functions that return boolean values and `assertIs...` functions that throw errors if assertions fail, making it valuable for developers working with libraries like xpath and @xmldom/xmldom who need to validate DOM node types.
