I have an array of objects in javascript. Each object is of the form

obj {

    location: left, // some string

    weight: 0 // can be zero or non zero

}

I want to return a filtered copy of the array where the objects with a weight property of zero are removed

What is the clean way to do this with underscore?

You don't even really need underscore for this, since there's the filter method as of ECMAScript 5:

var newArr = oldArr.filter(function(o) { return o.weight !== 0; });

But if you want to use underscore (e.g. to support older browsers that do not support ECMAScript 5), you can use its filter method:

var newArr = _.filter(oldArr, function(o) { return o.weight !== 0; });
