You want to build a word cloud, an infographic where the size of a word corresponds to how often it appears in the body of text.

word-cloud-data.js

var inputString = 'We came, we saw, we conquered...then we ate Bill\'s (Mille-Feuille) cake.'

function(inputString){
  var words = [];
  for(var i=0;i<inputString.length;i++){
    var word = [];
    var stringElem = inputString[i];
    word.push(stringElem);
    if(stringElem === ' ' || stringElem === ',' ){ // marks the end of word
      words.push(word);
      continue;
    }
  }
  
  
}
