I've got the following nodejs function that retrieves an api's data (JSON) and tries to erase all the 0 Balance elements and send the JSON to frontend.
我有以下nodejs函数检索api的数据（JSON）并尝试擦除所有0 Balance元素并将JSON发送到前端。
app.get('/getapibittrex', function(req, res){
var url="https://bittrex.com/api/v1/account/getbalances?apikey="+req.query.apikey;
request({
url: url,
json: true
}, function (error, response, body) {
if (!error && response.statusCode === 200) {
var datos= body.result;
for ( var i = 0 ; i < datos.length; i++ ) {
if (datos[i].Balance==0) {
datos.splice(i,1);
}
}
res.send(datos);
} else {
console.log("Error calling API: "+error);
}
});
});
On the other hand when i call this function i get elements with 0 balance!! What i am getting now is:
另一方面，当我调用此函数时，我获得了0余额的元素！我现在得到的是：

You can use Array.prototype.filter and do not reinvent the wheel.
您可以使用Array.prototype.filter并且不要重新发明*。
var datos = body.result.filter(function(data){
return !!data.Balance;
});
