Discord.js how to get user id just from the username

Question

This isn't working: client.users.cache.get(`${args[0]}`).id;

What should I do to fix it? I'm on v12

Answer 1

Try

matching_client = client.users.cache.filter(user => user.username === args[0]);

matching_client is a Collection of users that match that username
