Getting the values for a specific key from all objects in an array

Question

I\'m running an express.js app that has a few apis feeding data to dropdown boxes. The data returned is in the form:

  [
    {
        key: \'blah\',
                


        

Answer 1

In the current versions of Javascript you need a loop do to it.

However you can use a module like npm `lodash' to make it look simpler

var _ = require('lodash')
var permittedValues = _.pluck(array, 'key')
