Is a JavaScript library to verify and format phone numbers. It is similar in purpose to Google's libphonenumber library, with the main difference that Google's code is some incredibly ugly spaghetti code that was cross-compiled from Java and uses around 10MB of memory.
The memory use of PhoneNumber.js starts around 60k and increases as region meta data is unpacked. Depending on the memory layout of the specific JavaScript engine, peak memory use should be below 200k. If you mostly format numbers from one or a few regions, memory use should be pretty close to 60k.
PhoneNumber.js uses libphonenumber's PhoneNumberMetadata.xml database of known phone number formats. Use "make" to download the xml file and translate it into PhoneNumber.js's internal format.
