How do i point two fields to use the same value in javascript

I have this Object below, and as you can see, "valid" and "pending" are using the same value, is there a way to put this in one line rather than duplicating "custom-info" ?

  Map = {
    'failed': 'custom-error',
    'pending': 'custom-info',
    'valid': 'custom-info'
  };

Map = {
  'failed': 'custom-error'
};
Map.pending = Map.valid = 'custom-info';

This will get you a shorthand, but remember that strings, being primitives, are passed as copies, and this may not behave as you need.

Enum = {
  'error': 'custom-error',
  'info': 'custom-info'
};

Map = {
  'failed': Enum.error,
  'pending': Enum.info,
  'valid': Enum.info
};

If you need actual references to objects, I suggest:

Enum = function(type) {
  var keys = {
      error : { text: "custom-error" },
      info : { text: "custom-info" }
  };

  return keys[type];
};


Map = {
  'failed': Enum('error'),
  'pending': Enum('info'),
  'valid': Enum('info')
};

You can assign string value to constant and set property value using constant.

const CUSTOMER_INFO = 'custom-info';
Map = {
    'failed': 'custom-error',
    'pending': CUSTOMER_INFO,
    'valid': CUSTOMER_INFO
  };

This helps only if setting property value many times and used somewhere else also otherwise setting string value in object is fine.
