-It is true that [fastest-json-copy](https://www.npmjs.com/package/fastest-json-copy) may be faster, BUT it has such huge limitations that it is rarely useful. For example, it treats things like `Date` and `Map` instances the same as empty `{}`. It can't handle circular references. [plain-object-clone](https://www.npmjs.com/package/plain-object-clone) is also really limited in capability.
+It is true that `jsondiffpatch.clone()` from [jsondiffpatch](https://www.npmjs.com/package/jsondiffpatch) is the fastest in that benchmark run, but it cannot handle as many situations as `rfdc` can. Also, [this](https://www.measurethat.net/Benchmarks/ShowResult/202870) and [this benchmark result](https://www.measurethat.net/Benchmarks/ShowResult/202871) suggest that `rfdc` is faster in Firefox and Chrome at [this different benchmark](https://www.measurethat.net/Benchmarks/Show/13538/3/lodash-clonedeep-vs-jsonparsejsonstringify-vs-fastest-j).

+It is true that [fastest-json-copy](https://www.npmjs.com/package/fastest-json-copy) is faster than `rfdc` in this particular benchmark, but we have seen that, [with different input](benchmark/fixture2.json), the opposite is true. Also, fastest-json-copy has such huge limitations that it is rarely useful. For example, it treats things like `Date` and `Map` instances the same as empty `{}`. It can't handle circular references.
