Discord.JS Message react with "standard" emojis

Question

So... I've started a while ago with Discord.JS, and I have been searching and searching, but I just can't really find how to react to message with "standard" Discord emojis. I mean...

https://i.stack.imgur.com/gLeHx.png - those emojis.

I want to do something like this:

execute(client, message, args) {
    message.content.toLowerCase();

    message.channel.send('Something...').then(resource => {
        resource.react('${args}');
    });
}

args = 842839246934114324 (:smile: emoji)

Answer 1

Get emoji by unicode symbol:

You need to copy the unicode symbols (copy them from discord or from a website like this one ):

And then just say message.react('✅')

You can get the unicode emojis from discord by sending the emoji as you noramlly would and prepending \ before it. This will write the emoji as a unicode symbol which you can just copy into your code.

eg: instead of :laughing: type \:laughing:

Get emoji by Id (only works with custom emojis):

const emoji = message.guild.emojis.resolve(id);
// OR
const emoji = client.emojis.resolve(id);

message.react(emoji);

Answer 2

    message.chanenl.send("hi").then(msg=>{
    msg.react("ID")
  // OR
    msg.react("✅")
  // OR

  //V 11
   let emoji = client.emojis.get("ID")
  //V 12
   let emoji= client.emojis.cache.get("ID")
   if(emoji) return msg.react(emoji)
 })

Adding onto MrCodingB's response: Getting a native Unicode symbol from discord emojis is actually really easy; all you need to do is add an emoji and add a \ in front of it, then send the message:) Although this is possible I personally use getemoji.com.
