Can a bot give me a higher role discord.js code example

Example 1: get discord.js role

let role = message.guild.roles.cache.find(r => r.id === "Role ID");

// The member you want to add the role to
let member = message.mentions.members.first();

// Add role to the member
member.roles.add(role);

// Or add it to yourself
message.author.roles.add(role);

Example 2: discord.js v12 how to set owner commands

// First we use guild.members.fetch to make sure all members are cached
<message>.guild.members.fetch().then(fetchedMembers => {
	const totalOnline = fetchedMembers.filter(member => member.presence.status === 'online');
	// We now have a collection with all online member objects in the totalOnline variable
	<message>.channel.send(`There are currently ${totalOnline.size} members online in this guild!`);
});
