这段 js 代码有简洁的写法吗?

var emails = [];
result.userList.map((item) => {
    emails.push(item.mailAccount);
})
$("#confirm_users").html(emails.join("<br/>"))

这才 fp

const prop = (id) => (obj) => obj[id]
result.userList.map(prop('mailAccount')).join(’<br />’)

pipe(
  prop('userList'),
  map(prop('mailAccount')),
  join('<br />')
)
