Proposal for Introducing nil to ECMAScript

Abstract

This proposal aims to introduce a new primitive value nil to the ECMAScript language, addressing a gap between null and undefined. While seemingly unnecessary, this addition offers subtle and nuanced differentiation in handling non-values, aligning with modern programming paradigms.

Specification

• Value: nil
• Type: typeof nil returns "absent"
