Playing devil’s advocate: Is Dict really necessary? Whenever performance doesn’t matter (as much), I’d advocate Map. Otherwise, I’d expect programmers who want the extra speed to be comfortable with Object.create(null). Assumptions about Dict: - You still can’t use the key '__proto__'. - You can’t invoke any methods on it. How will it implement the iteration protocol? -- Dr. Axel Rauschmayer [email protected]<mailto:[email protected]> home: rauschma.de<http://rauschma.de> twitter: twitter.com/rauschma<http://twitter.com/rauschma> blog: 2ality.com<http://2ality.com>
