Discord is designed as a communication app for gamers.
The voice chat channels are a big part of that functionality that specifically enables in-game communication.
The text chat channels are the other key part of communication over Discord.
There are plenty of use cases for the text channels, from memes to long-form discussions.
Occasionally you may want to respond or acknowledge a message without actually sending a full message yourself.
Helpfully, Discord allows you to do so with the Reaction feature.
Reactions are just emoji that you could put next to any post.
Underneath all of the custom emoji are the standard Discord emoji that work everywhere.
Scroll through the emoji picker, then choose the emoji you want to react with.
If someone has already reacted with the emoji you want to react with, you might just select it.
