hast-util-to-string is a utility that extracts the textual content from a Hast (Hypertext Abstract Syntax Tree) node. It traverses the tree, concatenating text nodes' values and ignoring other node types. This is useful for obtaining a plain text representation of HTML content represented as a Hast tree, often used in tasks like indexing, searching, or generating previews. The package provides a simple and efficient way to strip away the markup and focus solely on the textual information contained within the Hast structure.
