What's the best way to query an array in javascript to get just the items from it I want?

Question

I have an array like this (with just over 3000 objects instead of the 3 here):

items = [{name:\'charlie\', age:\'16\'}, {name:\'ben\', age:\'18\'}, {name:\'s

No matter which method you choose (items.filter or any "query language" for json), a for loop is inevitable.

If performance is a concern, I would recommend you to use pure javascript instead of libraries like jQuery which will add overheads to the whole processing as is evident here.

Thus, your code would look like:

var newArray = [];
for(var i=0;i
