Remove items from dynamic array [duplicate]

Question

I have a dynamic array (chat messages), like

{
 id:1,
 message: bla-bla
},
{
 id:2,
 message: bla-bla
},
{
 id:1,
 message: bla-bla
},
{
 id:1,
 message: bla-bla
},
{
 id:3,
 message: bla-bla
},
{
 id:4,
 message: bla-bla
}

How to leave in array only items with id:1, or remove all items where id not 1

You can make use of .filter() and only return items where the id is equal to 1.

var newArr = yourArray.filter(function(item) {
  return item.id === 1
});

And for more info and the .filter() shim for older browsers - click here
