Some schema libraries support two way conversion of data, often referred to as "encoding" and "decoding".

We benchmark the time taken to encode and decode a Date to and from a string (usually an ISO 8601 string, but we don't enforce this).

import * as z from "zod";

const dateFromString = z.codec(z.iso.datetime(), z.date(), {
  encode: (date) => date.toISOString(),
  decode: (str) => new Date(str),
});

dateFromString.encode(new Date(0)); // "1970-01-01T00:00:00.000Z"
dateFromString.decode("1970-01-01T00:00:00.000Z"); // Date

format_quoteInvalid data

We don't benchmark codecs with invalid data, as many libraries require the input to be correctly typed before passing it to the codec.
