javascript - Mapping out JSON structure -

i'm parsing json message looks like:

{      staff : [        {name : 'john', department : 'math'},        {name : 'sally', department : 'science'},     ],     students : [        {name : 'bob', department : 'law'},        {name : 'lisa', department : 'it'}     ] } 

from i'd pull out array of each separate value. i.e.

names -> ['john', 'sally', 'bob', 'lisa'] 

at moment i'm doing like

var names = []; msg.staff.foreach(function(e) { names.push(e.name) }) msg.students.foreach(function(e) { names.push(e.name)}) 

this feels overly verbose, wondering if there's cleaner way approach (for every attribute). i'm including lodash in project.

you can use _.pluck value of property of each object in array:

_.pluck(obj.staff.concat(obj.students), 'name')
