I have a list of saved items in a Mongo collection, I'd like to know how to filter the original array. Follow the code

api.filtra = function (req, res) {
    model.find()
        .then(function(itens) {
            for(i = 0; i < itens.length; i++)
                console.log(itens[i].criterio);                
                res.json(itens);

                console.log("testeA");
                var filtrado = itens.filter(
                    itens, {"genero": "0"}
                );
                console.log("testeB");               
                console.log(filtrado);
        }, function (error) {
            console.log(error);
            res.sendStatus(500);
        });
}

The problem with this code is that it crashes when it's time to run "itens.filter", the last thing it displays on the console is "testA" Home What I would like to do is, for example, say I have people in this array, pass as a parameter via url the age, more or less like '/ v1 / people / age / x' where x is the age chosen by the user, and so just send the list to the browser with people who already meet this criteria. Home I hope I have been able to explain my doubts well, but if you have been confused tell me that I will try to rephrase my question. Home Thank you all right away.

Why do not you let mongodb do this for you, search on mongodb using the querry of it ... ex:

model.find({idade:req.query.idade}).then((result) => {
     res.json(result)
}, (err) => {
     res.status(500).json({error: err})
})

This way you could call it like this: / api / people? age = 15. I recommend that you study one of the standards of an api RestFull
