How to parse milliseconds to date in React-native

Question

I am getting date from in this format "/Date(1471846675177+0000)/"
I have done this :

var longToDate=function(millisec){
    var length=millisec.length-7;
    var date=millisec.substring(6,length);
    return (new Date(millisec.substring(6,length)).toUTCString());
} 

But it is showing "invalid date". Can someone tell me the reason for it ?

Answer 1

you forgot parseInt

var longToDate = function(millisec) {
    var length = millisec.length - 7;
    var date = parseInt(millisec.substring(6,length));
    return (new Date(date).toUTCString());
}
