lodash helpers - rename (renames object keys)

rename.js

/*
* var person = { firstName: 'bill', lastName: 'johnson' }
* 
* person = _.rename(person, 'firstName', 'first')
* person = _.rename(person, 'lastName', 'last')
*
* console.log(person) // { first: 'bill', last: 'johnson' }
*/

_.rename = (obj, key, newKey) => {
  if(_.includes(_.keys(obj), key)) {
    obj[newKey] = _.clone(obj[key], true)
    delete obj[key]
  }
  return obj
}

• replaced _.contains with _.includes so it'll work with lodash 4.x
• updated to use arrow function and removed semi-colons

works great! 👍

Thanks! I modified it to handle dot syntax for deeply nested props:

import { get, set, unset, has } from 'lodash'

export default (obj, oldKey, newKey) => {
  if (has(obj, oldKey)) {
    set(obj, newKey, get(obj, oldKey))
    unset(obj, oldKey)
  }
  return obj
}
