Perform .join on value in array of objects

Question

If I have an array of strings, I can use the .join() method to get a single string, with each element separated by commas, like so:

[\"Joe\", \"         


        

Answer 1

I don't know if there's an easier way to do it without using an external library, but I personally love underscore.js which has tons of utilities for dealing with arrays, collections etc.

With underscore you could do this easily with one line of code:

_.pluck(arr, 'name').join(', ')
