jsprim: JavaScript Primitive Utilities

jsprim is a utility library focused on fundamental operations for JavaScript primitive types and common object manipulations. It provides functions for deep cloning, thorough deep equality comparisons, and efficient inspection/transformation of object structures, including an O(1) `isEmpty` check and memory-efficient `flattenIter` for traversing deeply nested objects without materializing the full result array. The current stable version is 2.0.2, with the last update approximately four years ago. It targets older Node.js environments (originally requiring Node.js >=0.6.0) and uses the CommonJS module system, making it suitable for legacy projects or environments where explicit CJS interop is managed.
