momentjs startOf does not work on existing date object

Question

I\'m trying to use moment to get the start of a day. I get different results with the following:

moment().startOf(\'day\'); //good
moment(new Date()).startO         


        

Answer 1

I suggest to use format() to display the value of a moment object.

As the Internal Properties guide states:

Moment objects have several internal properties that are prefixed with _.

The most commonly viewed internal property is the _d property that holds the JavaScript Date that Moment wrappers. Frequently, developers are confused by console output of the value of _d.

...

To print out the value of a Moment, use .format(), .toString() or .toISOString()

Here a snippet showing the correct results:

console.log(moment().startOf('day').format());
console.log(moment(new Date()).startOf('day').format());
