Check if date is a valid one
date, datetime, javascript, momentjs
Solution
Was able to find the solution. Since the date I am getting is in ISO format, only providing date to moment will validate it, no need to pass the dateFormat.
var date = moment("2016-10-19");
And then `date.isValid()` gives desired result.
Problem
Following is the scenario: I have a `String` date and a date format which is different. Ex.: date: 2016-10-19 dateFormat: "DD-MM-YYYY". I need to check if this date is a valid date. I have tried following things ``` var d = moment("2016-10-19",dateFormat); ``` `d.isValid()` is returning `false` every time. Does not Moment.js parse the date in the given format? Then I tried to format the date in `DD-MM-YYYY` first and then pass it to Moment.js: ``` var d = moment("2016-10-19").format(dateFormat); var date = moment(d, dateFormat); ``` Now `date.isValid()` is giving me the desired result, but here the Moment.js date object is created twice. How can I avoid this? Is there a better solution? FYI I am not allowed to change the `dateFormat`.
