This document discusses proposals for implementing value objects in JavaScript. Some key points include: - Value objects could represent common types like integers, floats, and SIMD vectors, as well as mathematical constructs like big numbers, decimals, and complexes. - Overloadable operators like +, -, *, / would allow defining behaviors for mathematical operations on different value object types. - To preserve boolean identities, != and ! cannot be overloaded, and relations like > would be derived from <=. - Strict equality operators === and !== cannot be overloaded and test structural equality. - An approach using cacheable multimethods avoids issues with double dispatch and allows defining operators between types. - Literal
