• 3 The error message is pretty clear; at that point in your code, message is not defined anywhere. What did you expect it to be? – Phil Commented Jul 2, 2020 at 3:20
• I watched this video, as i said i am new to javascript and discordjs. how would i define it youtube./watch?v=Ygc04PcjoLk&t=223s – Gelvey Commented Jul 2, 2020 at 3:26
• 1 Is this a typo? JavaScript is case-sensitive, and your code is using Message everywhere except in the line with the error (and in some ments....) Should the line with the error be let args = Message.content.slice(prefix.length).trim().split(' '); instead? – ad absurdum Commented Jul 2, 2020 at 3:51
• Still doesnt work – Gelvey Commented Jul 2, 2020 at 4:29
• 4 Well, Message still needs to be defined so you probably want to move the code into the scope which has Message defined. I.e. client.on('Message', Message => {... let args = Message.content.slice(prefix.length).trim().split(' '); } – Sam Gomena Commented Jul 2, 2020 at 4:50

JavaScript is case sensitive.

clinet.on("message", Message => {});

In the following you defined message parameter with a capital "M".

So you need to mention the Message with a capital M.

Here's the fix for args V

let args = Message.content.slice(prefix.length).trim().split(' ');

Hope This helps.
