  ECMAScript proposal for the Record and Tuple value types. | Stage 2: it will change!

  

JavaScript has no feature like this, but there is a current proposal to add a "record" primitive type which is a key/value object with value semantics. These would be immutable though, which doesn't seem like it fits your need, as it seems like you want something which is copied by default but still mutable.
