Alexa Skills use slotValue as array name

Question

if (slotValues.listableThings.ERstatus === 'ER_SUCCESS_MATCH') {
  switch (slotValues.listableThings.resolved) {
    case 'CLASSES':
      {
        lookupArray = sessionAttributes.CLASSES;
      };
      break;
   case 'TONES':
      {
         lookupArray = sessionAttributes.TONES;
      };
      break;
    default:
      break;
  }

Is there a way to do this instead of using a switch to just set lookupArray = sessionAttributes.(slotValues.listableThings.resolved)

everything I can find on javascript says to use alert but alert is not defined in node.js for alexa skills.

You can iterate thought the elements and use the key to assign

// Emulating 
var slotValues = {
  listableThings: {
    resolved: "CLASSES"
  }
};

var sessionAttributes = {
  CLASSES: "THESE ARE CLASSES",
  TONES: "THESE ARE TONES"
}

let lookupArray = sessionAttributes[slotValues.listableThings.resolved];

console.log(lookupArray);
