ReferenceError: bot is not defined - discord

Question

This is something with the const or var. I think that it won't work unless I recode it. Here is my problem:
bot.on('ready', () => {
^

I have looked all over for answers but nothing seems to work. I end up with this in cmd prompt when I try to run it

Answer 1

Where you're requiring the library you need to change it to discord.js to get access to the library.
Also the library does not expose a class called "Bot" so you need change that to "Client".
I'm guessing the )}; on line 5 is supposed to be closing the ready event on line 88.
But I suggest you just stick with one ready event, so put the status and activity methods in the first ready event and remove the other ones. Also, if you've set your bot username to what you want I would remove that method, or put a check to see if the username is already set to what you want, and if it is then don't change it.
Same with all the message events as the ready ones, stick to one message event and just chain all the if statements in that one. Example:
bot.on('message', message => {
if (message.content === '!ping') {
message.channel.send('pong');
}
else if (message.content === '!apply') {
message.channel.send('GOGLE STUFF');
}
...
});
Also you need to remember what you define your variables as. In the first ready event you use client.users instead of what you have defined, which is bot.

According to discord.js API document, there is no Bot class.
Maybe what you need is
const client = new Discord.Client();
I suggest you check the document and example for your application.
