Pluck has been removed from lodash 4. This is because it did the same thing as a map.
As a replacement, you can use the map function in the following way −
Example
import _ from 'lodash'
const objects = [{ 'a': 1 }, { 'a': 2 }];
console.log(_.map(objects, 'a'))This will give the output −
Output
[1, 2]
