I'm mapping through array of objects and apply condition on each object by adding a new value according to the condition. I use map in ramda. Can I do this better?

Here's my code in javascript:

events = map(el => {
  if (!['ts', 'sxi', 'ht', 'hd'].includes(el.value)) {
    el['extras'] = {type: 'cx', label: 'Es', name: 'es', options: ['cf']}
  }
  return el;
}, events);
