HAST Property Checker

hast-util-has-property is a focused utility within the unified (specifically HAST) ecosystem, designed to ascertain if a given HAST (Hypertext Abstract Syntax Tree) element node possesses a specified property. The current stable version is 3.0.0. This package is maintained by the syntax-tree collective, aligning its release cadence with Node.js LTS versions and the broader `unified` project's evolution, frequently releasing new major versions to adopt modern JavaScript features like ESM. Its primary differentiation lies in its tight integration with the HAST specification, providing a type-safe (TypeScript-enabled) and robust method for property checking, crucial for HTML processing pipelines. It is a highly specialized tool, typically used by developers working directly with HAST manipulation, offering a reliable primitive for conditional logic based on element properties in transform plugins. It strictly operates on valid HAST `Node` objects, particularly `Element` types, providing a precise `boolean` result.
