For simple attribute based searches you can use Collection#where:
where
collection.where(attributes)Return an array of all the models in a collection that match the passed attributes. Useful for simple cases of
filter.
So if friends is your Friends instance, then:
var lees = friends.where({ name: 'Lee' });
There’s also Collection#findWhere (a later addition as noted in the comments):
findWhere
collection.findWhere(attributes)Just like where, but directly returns only the first model in the collection that matches the passed attributes.
so if you’re only after one then you can say things like:
var lee = friends.findWhere({ name: 'Lee' });
