SImple JavaScript tokenize, cases, simple but nice to remember

word.js

  // is the word in camel-case? it should start with lower-case and have at least 1 upper-case

  // title-case must have 1st character as capital and no more
  isTitle 	= /^[A-Z]/g.test(word) ? (word.length - numCapitals) + 1 === word.length : false,
  // array from word split on upper-case characters or first lower, forced to all lower
