Object Size Calculator

The `object-sizeof` library provides an approximation of the memory footprint of a JavaScript object in bytes. Currently at stable version 2.6.5, the package sees active maintenance with minor releases addressing types and bug fixes, as evidenced by recent updates from v2.6.1 to v2.6.4. It distinguishes itself by employing separate underlying implementations for Node.js (utilizing `Buffer.from` on stringified objects) and browser environments (using a recursive stack-based approach). A key feature is its expanded support for a wide array of built-in and complex types including Map, Set, BigInt, Function, and Typed Arrays. Unlike some alternatives, `object-sizeof` aims for robustness by returning -1 for common error scenarios such as circular references or unrecognizable TypedArray objects, preventing exceptions or infinite loops, rather than throwing errors. It also ships with TypeScript types for improved developer experience.
