How do I format.created_at to produce the same time format as my Ruby code?

Javascript / jQuery

<script>
  setInterval(function () {
    fetch('/pages/markets.json')
    .then((response) => response.json())
    // .then((data) => console.log(data))
    .then((data) => { 
      $('#container').html('')
      data.forEach((item) => { 
        $('#container').append('<li><div id="created" class="text-xs mb-1">' + item.created_at + '</div><div id="text" >' +  item.tweet_text +'</div></li>')
      })

I think it's better to send formatted date to frontend from backend

But if you can't, you can use moment.js

moment(item.created_at).tz('America/New_York').format('hh:mm A')

or

moment.tz(item.created_at, 'EST').format('hh:mm A')

Please look:

https://momentjs.com

https://momentjs.com/timezone

You can also use vanilla JS Intl.DateTimeFormat

Intl.DateTimeFormat('en', { hour: '2-digit', minute: '2-digit', timeZone: 'EST' }).format(new Date(item.created_at))
