Im getting a "is not a function" error, and i have no why is happening, the issue is how i resolve in this case.

I have a data that is received from the user has string, and after i receive the data i need to clean this data,(replace commas by dots and than convert to number). The problem is after is sent the data to the server and comes back this data keeps in the application and than comes back to the server, the problem is that since in the first time the data already been treated is passing by a .replace function, and than gives me the error. How could i avoid in the second situation pass from being cleaned the data?

Here is my function:

var myNewData = _.map(oldData).map(function(x){
    return _.assign(x,{
        value_price: x.value_price ? parseFloat(x.value_price.replace(",", ".")) : null
    });
});

maybe add a type check `&& typeof x.value_price === 'string'` – Sander Sluis Jul 07 '16 at 11:53
Because your var x.discount_value_price is not a string (probably a float or int ?). – Ugo T. Jul 07 '16 at 11:54
sorry, i edit the code, i forgot to update all variables – Marco Santos Jul 07 '16 at 11:55
@UgoT. it could be a float or int, is price, decimal – Marco Santos Jul 07 '16 at 11:55
@MarcoPereira only Strings implement the `replace` method. So you need to make your logic type safe – Sander Sluis Jul 07 '16 at 11:58
