Run an alert when kintone value changes

Alert on changes when editing a record.

(function() {
  'use strict';

  // Data retention before editing
  let fruit_name;
   const RecordCheck = function(event) {
    fruit_name = event.record.fruit_name.value;
  }
  // Compare data on save
  const updateRecord = function(event) {
    if(fruit_name === event.record.fruit_name.value ) {
      console.log('No change in value')
    } else {
      // Execute when value changes
      alert('there was a change in values');
    }
 }

  const eventlist = [
    'app.record.edit.submit.success'
  ];
  kintone.events.on(eventlist, updateRecord);

  const eventlists = [
    'app.record.edit.show'
  ];
  kintone.events.on(eventlists, RecordCheck);
 
})();

If you modify the part that says "alert('there was a change in values');" there are many applications that could benefit from it.

For example, you can run your program only when the value of a field changes.
