LoDash: Get an array of values from an array of object properties

Question

Since version v4.x you should use _.map:

_.map(users, 'id'); // [12, 14, 16, 18]

this way it is corresponds to native Array.prototype.map method where you would write (ES2015 syntax):

users.map(user => user.id); // [12, 14, 16, 18]

Before v4.x you could use _.pluck the same way:

_.pluck(users, 'id'); // [12, 14, 16, 18]

With pure JS:

var userIds = users.map( function(obj) { return obj.id; } );

In the new lodash release v4.0.0 _.pluck has removed in favor of _.map

Then you can use this:

_.map(users, 'id'); // [12, 14, 16, 18]

You can see in Github Changelog

And if you need to extract several properties from each object, then

let newArr = _.map(arr, o => _.pick(o, ['name', 'surname', 'rate']));

Simple and even faster way to get it via ES6

let newArray = users.flatMap(i => i.ID) // -> [ 12, 13, 14, 15 ]
