Hi I'm having an array of date example `[2019-02-21T04:06:32.000Z]` and I want to convert the date into desired format `[02/21/2019 4:06:32 AM]`. So I'm using javascript map 

```
dateArray.map( x => {
   return moment.tz(x, 'Etc/UTC').format('MM/DD/YYYY h:mm:ss A').toString()
});

```

after this I console date array but it is still showing `[2019-02-21T04:06:32.000Z]` but inside map() it is showing in desired format. What I'm doing wrong here? Can any one help me to solve this? Thank you.
