This is a re-implementation of (most of) the Python struct module in JavaScript. It uses arrays of numbers between 0 and 255 in lieu of Python's strings, and omits some of the more obscure types (e.g. Pascal strings). It offers support for:

• Signed & Unsigned 8, 16, and 32 bit integers
• 32 and 64 bit floating point
• ASCII characters and strings
• Raw octet arrays
