The alert is used to print the value of the parameter "loading", which is "false" when the alert box pops up.
However this alert message should not be popped in theory, noticing that the conditional expression is contradictory with the semantics of the upper if-else statement. Remote data is correctly received and parsed, then "updateState" is called. So I don't think it's a problem with remote data.
