A Shimblance of Success
summary
Built-ins often run slower, behave inconsistently across engines, and shims are frequently partial or break specs; measurable regressions and traps crop up in things like bind, Object.defineProperties and string whitespace. Replacing shims with a thin library layer delivers consistent semantics, adds Lo-Dash library conveniences like callback shorthands, uses Set for uniqueness and enables optimizations such as binary-search lookups and shortcut fusion so many chains execute far fewer iterations and actually improve real-world performance.
