If you want to make some array to array replace, respecting the separators like "." or ",", I have created something like that that may help you.

function arrayReplace( text, arrFrom, arrTo, caseSensitive ) {
  return text.
    replace(//g,">> ").
    replace(/([\.\;\,])/g," <$1> ").
    split(" ").
    map(
      function(value) {
        var pos = arrFrom.indexOf( caseSensitive ? value : value.toLowerCase() );
        if( pos == -1 ) {
          return value;
        } else {
          return arrTo[pos % arrTo.length];
        }
      }
    ).
    join(" ").
    replace(/( \<|\> )/g,"");
};

console.log( 
  arrayReplace(
    "First example. Trivial case",
    [ "example", "case"],
    [ "demo", "test" ]
  )
); // First demo. Trivial test

console.log( 
  arrayReplace(
    "Leaving earth, passing close to the sun, going to the moon.",
    [ "earth", "sun", "moon"],
    [ "EARTH", "SUN", "MOON"]
  )
); // Leaving EARTH, passing close to the SUN, going to the MOON.

console.log( 
  arrayReplace(
    "Leaving earth, passing close to the sun, going to the moon.",
    [ "earth", "sun", "moon"],
    [ "PLANET"]
  )
); // Leaving PLANET, passing close to the PLANET, going to the PLANET.

console.log( 
  arrayReplace(
    "Leaving earth, passing close to the sun, going to the moon.",
    [ "earth", "sun", "moon"],
    [ "PLANET", "STAR" ]
  )
); // Leaving PLANET, passing close to the STAR, going to the PLANET.

console.log( 
  arrayReplace(
    "Rain rain, goes away, no one wants you any way.",
    [ "rain", "a"],
    [ "pig", "x"]
  )
);
// pig pig, goes away, no one wants you any way.

console.log( 
  arrayReplace(
    "Testing the <>. Replacing, in  case. Even .",
    [ "funny", "even", "function" ],
    [ "complex", "including", "code" ]
  )
); // Testing the <>. Replacing, in  case. including .
