Remove duplicates from dropdown list

I'm trying to generate a <select> dropdown list of subclassifications to create a filter. When the list is generated I get duplicates and strings. How do I split the strings and then remove duplicates?

EXAMPLE - This is what I current get

<select data-filter="" class="form-control" name="subClassifications">
    <option value="all">Select sub-classification</option>
      <option value="Audit">Audit</option>
      <option value="Assurance,Accounting,Audit">Assurance,Accounting,Audit</option>
</select>

Path: helper.js

subClassificationsFilter() {
  let subClassifications = ProfessionalOverview.find( {}, { fields: { subclassification: 1 } } );

  if ( subClassifications ) {
    return _.uniq( subClassifications.map( ( subClassification ) => {
      return subClassification.subclassification;
    }), true );
  }
},

    subClassificationsFilter() {
        let subClassifications = ProfessionalOverview.find( {}, { fields: { subclassification: 1 } } ).fetch();
        let subClassification = _.map(subClassifications, function(obj) {
            return obj.subclassification;
        });

        let groupSubClassification = _.flatten(subClassification);

        return _.uniq(groupSubClassification).sort();
  }

Create a list to remove duplicates

unorderedList = Object.keys(myObject).map(function(key){
    return {label: key, value: myObject[key]}
});

Then order the unordered list

const orderedList = {};
Object.keys(unorderedList).sort().forEach(function(key) {
    orderedList[key] = unorderedList[key];
});

Use the ordered list to create your dropdown.
