What is the difference between lodash's _.map and _.pluck?

Question

I have the following code, can anyone tell the difference:

const _ = require(\'lodash\');

const arr = [
    {\'fname\':\'Ali\', \'lname\': \'Yousuf\'},
             


        

Answer 1

In the way you're using them, they basically do the same. That's why .pluck() was removed from Lodash v4.0.0 in favor of using .map() with a string as second argument.

Here's the relevant excerpt from the changelog:

Removed _.pluck in favor of _.map with iteratee shorthand

var objects = [{ 'a': 1 }, { 'a': 2 }];

// in 3.10.1
_.pluck(objects, 'a'); // → [1, 2]
_.map(objects, 'a'); // → [1, 2]

// in 4.0.0
_.map(objects, 'a'); // → [1, 2]
