I wanted a circular array to use as a fixed-length buffer for receiving data in a streaming JSON parser I wrote: https://github.com/philbooth/bfj/blob/61087c194d5675c75569a2...

A circular array type, love it! It looks like an excellent use case of proxies.

Technically the type should still be an Array with the backing implementation having a circular array behavior no?

Indeed, it extends native Array: https://github.com/philbooth/hoopy/blob/master/index.js#L3

Cool. I was seeing source of inner js, which in deed uses proxies to create structural sharing.
