The additions of a standard JSON parsing mechanism and strict mode will be of great benefit to developers, with the potential to translate into smaller libraries for Prototype and other extension libraries required. Parsing ISO dates from a JSON stream now becomes much more portable than before, and looks likely to be the de facto standard for representing dates in the future. Lastly, since this is backwardly compatible and takes cues from existing libraries like Prototype, it is likely that developers and web browsers alike will take to the new features of JavaScript in the near future.
