Handlebars.registerHelper('nl2br', function (text, isXhtml) {
  var breakTag = (isXhtml || typeof isXhtml === 'undefined') ? '<br />' : '<br>';

Here is a handlebars each new line plugin
https://gist.github.com/dhollenbeck/c4cde67aee08a3db06edf34c02ddd543

this version reuses the internals from Handlebars in accordance with the docs:

Handlebars.registerHelper('nl2br', function(text, isXhtml) {
  const breakTag = isXhtml ? '<br />' : '<br>'
  const withBr = Handlebars.escapeExpression(text).replace(
    /([^>\r\n]?)(\r\n|\n\r|\r|\n)/g,
    '$1' + breakTag + '$2'
  )
  return new Handlebars.SafeString(withBr)
})
