Given:

[{     'id':1,     'name':'john' },{     'id':2,     'name':'jane' }........,{     'id':2000,     'name':'zack' }] 

What's the best way to get:

['john', 'jane', ...... 'zack'] 

Must I loop through and push item.name to another array, or is there a simple function to do it?

Answer 1

If your array of objects is items, you can do:

var items = [{    id: 1,    name: 'john'  }, {    id: 2,    name: 'jane'  }, {    id: 2000,    name: 'zack'  }];    var names = items.map(function(item) {    return item['name'];  });    console.log(names);  console.log(items);

Use the map() function native on JavaScript arrays:

var yourArray = [ {     'id':1,     'name':'john' },{     'id':2,     'name':'jane' }........,{     'id':2000,     'name':'zack' }];  var newArray = yourArray.map( function( el ){                                  return el.name;                                 });
