…fy like we do for Object.assign Merge pull request #4907 from sethbrenith:user/sethb/stringify-cache-iter JSON payloads tend to be relatively repetitive, so we can save a lot on large serializations by reusing object property iteration. On a microbenchmark that serializes and parses a repetitive piece of data that I found in Speedometer, I see a 35% improvement.
