Flavors

• numToWords
  • Usage:

var words = numToWords(123);
console.log(words); // "one hundred twenty-three"

• makeNumStrToWordsHP (High Performance)
  • You don't need this, just use numToWords().
  • Details:
    • Returns a closure function, relieving the need to redeclare functions and variables every time a function call is made.
    • Further performance tweaks rely on the argument number pre-converted to a string.
    • No error checking.
  • Usage:

var numToWordsHP = makeNumToWordsHP();
var words = numToWordsHP('123'); // NOTE: Argument is quoted.
console.log(words); // "one hundred twenty-three"

• numToJP and makeNumStrToJPHP
  • Same as above but returns in Japanese.
  • Usage:

console.log(numToJP(123)); // "百二十三"
