OxJs - jQuery for your Bytes

OxJs (speak: HexaJs) is a utility library for javascript, that facilitates parsing and creation of binary data in Javascript. While this sounds weird in the first moment, there are a few areas where OxJs can come in handy:

• If you need to transfer huge amounts of numercial data via AJAX, binary encoding can be much more space-efficient than transfering it in JSON. The number 41239 for example needs 5 Bytes in JSON, but only 2 Bytes in binary encoding (unsigned short). A more practical example is the The Google Maps Polyline Utility, which saves over 80% of the json payload by binary encoding. However, de- and encoding binary information can be a quite tricky and this is were OxJs helps.

• For client-side file parsing: Recent enhancements in Javascript allow us byte access for to-be-uploaded files. This can be used to perform enhanced sanity che
