Mention users and roles in Discord.JS v12

// Both are assuming you already have access to a channel variable

// Roles. You can get the ID from role.id
const roleId = '741229944927158315'
channel.send(`Hey <@&${roleId}>!`)

// Users. You can get the ID from member.id, user.id, etc.
const userId = '251120969320497152'
channel.send(`Hey <@${userId}>`)
