the object to use

The callback function(key, value) to invoke for each property.

key: The name of the current property.
value: The value of the current property.
this: The given context. If not set, the object itself.
(callback return value): true to include the property in the new object, false to omit it.

a context to pass to the callback as 'this'.

the new object

Creates a new object that contains only those properties of the input object that have been approved by the filter function.

If the callback function returns true, the property and its value are shallow-copied in the new object, otherwise it will be removed.

Removing all values over 10 from an object:

var list = _.filterObj({a: 4, b: 22, c: 7, d: 2, e: 19}, function(key, value) {
    return value <= 10;
});
