Exemple:

var lettresEnChiffres = function(str) {
  var array = {
    "neuf mil(le(s)?)?": "9000+",
    "huit mil(le(s)?)?": "8000+",

Voir aussi ce qui a été fait pour les chiffres romaines (afin d'éviter d'utiliser eval().

const romainVersArabe = (romain) => {
  const lookup = {
    I: 1,
    V: 5,
    X: 10,
    L: 50,
    C: 100,
    D: 500,
    M: 1000,
  };
  let arabe = 0;
  let i = romain.length - 1;
  const tempRomain = romain.toUpperCase();

  for (i; i >= 0; i -= 1) {
    if (lookup[tempRomain[i]] < lookup[tempRomain[i + 1]]) {
      arabe -= lookup[tempRomain[i]];
    } else {
      arabe += lookup[tempRomain[i]];
    }
  }

  return arabe;
};

Il faudrait ajouter les chiffres dans un tableau et additionner le tout une fois le processus de reconnaissance fini.
