How to split array dynamically based on single value in JavaScript Node.js -

i need split array dynamically based on single value in javascript.

i've got array:

var datastuff = [     { name: 'apple', tag: 'fruit', price: '2,5'},     { name: 'bike', tag: 'sport', price: '150'},     { name: 'kiwi', tag: 'fruit', price: '1,5'},     { name: 'knife', tag: 'kitchen', price: '8'},     { name: 'fork', tag: 'kitchen', price: '7'} ]; 

and expect arrays split tag, eg.

var fruit = [     { name: 'apple', tag: 'fruit', price: '2,5'},     { name: 'kiwi', tag: 'fruit', price: '1,5'} ];  var sport = [     { name: 'bike', tag: 'sport', price: '150'} ];  var kitchen = [     { name: 'knife', tag: 'kitchen', price: '8'},     { name: 'fork', tag: 'kitchen', price: '7'} ]; 

if in datastuff array more tags in result more arrays. anyway don't have idea how should this. i'm using node.js + jade (for view), , think best idea @ view because have put each array in table. maybe this:

// basic table tbody      - each item in datastuff          tr             td= item.name             td= item.tag             td= item.price  // other tables - each item in datastuff     item.tag.push(item);     // adding items array based on tag     // won't work      // still how should draw table? 

i grateful help

you use object grouped items. works tags , allows list of tags object.keys(grouped), if required.

var datastuff = [{ name: 'apple', tag: 'fruit', price: '2,5' }, { name: 'bike', tag: 'sport', price: '150' }, { name: 'kiwi', tag: 'fruit', price: '1,5' }, { name: 'knife', tag: 'kitchen', price: '8' }, { name: 'fork', tag: 'kitchen', price: '7' }],      grouped = object.create(null);    datastuff.foreach(function (a) {      grouped[a.tag] = grouped[a.tag] || [];      grouped[a.tag].push(a);  });    document.write(object.keys(grouped));  document.write('<pre>' + json.stringify(grouped, 0, 4) + '</pre>');
