How to fix SyntaxError: Unexpected Token '| |'

I am currently learning JavaScript by setting up audio functions to my Discord bot using node.js and I receive the following error when I execute 'node .' to my Terminal below trying to turn my Discord bot online in my test server:
SyntaxError: Unexpected token '||'

Here is my code related to the error on index.js:
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '-';
const fs = require('fs');
client.commands = new Discord.Collection();
client.events = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for(const file of commandFiles){
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
console.log("registering command", file, command.data?.name);
}
[ 'command_handler', 'event_handler'].forEach(handler =>{
require(`./handlers/${handler}`)(client, Discord);
})
client.on('guildMemberAdd', guildMember =>{
let welcomeRole = guildMember.guild.roles.cache.find(role => role.name === 'Member')
guildMember.roles.add(welcomeRole);
guildMember.guild.channels.cache.get('1016009653131411557').send(`Welcome <#${guildMember.user.id}> to the Velvet Room!`);
});
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(" ");
const command = args.shift().toLowerCase();
if(command === 'ping'){
client.commands.get('ping').execute(message, args);
} else if (command == 'twitter'){
message.channel.send('https://twitter.com/menevraa')
}
if(command === 'clear'){
client.commands.get('clear').execute(message, args);
} else if (command === 'play') {
client.commmands.get('play').execute(message, args);
} else if (command === 'leave') {
client.commands.get('leave').execute(message, args);
}
});
client.login('(key)');
And here is the code on event_handler.js as folks have pointed out the error is related to:
const fs = require('fs');
module.exports = (client, Discord) =>{
const load_dir = (dir) =>{
const event_files = fs.readdirSync(`./events/${dir}`).filter(file => file.endsWith('.js'));
for(const file of event_files){
const event = require(`../events/${dir}/${file}`);
const event_name = file.split('.')[0];
client.on(event_name, event.bind(null, Discord, client));
}
}
['client', 'guild'].forEach(e => load_dir(e));
}
The syntaxError did not show before I was setting up additional event and audio functions to my Discord bot, and I have attempted changing the code to:
if(!message.content.startsWith(prefix) || message.author.bot) return;
with this code instead:
if(!content.message.startsWith(prefix) || message.author.bot) return;
But it did not fix the error.

The || was added in a newer version of node. Try to update node to the latest version and launch your bot again ;)

TypeError: Cannot read properties of undefined (reading 'toJSON') - Discord.js slash commands

I tried making slash commands today on Discord.js, but my console threw some errors that it cannot read the property toJSON what can be the possible solution to it?
Here are my errors:
~/.../stuff/hazy $ node hazy.js
/storage/emulated/0/stuff/hazy/hazy.js:163
commands.push(command.data.toJSON());
^

Here is my code:
const { REST } = require('#discordjs/rest');
const { Routes } = require('discord-api-types/v9');
const { token } = require('./config.json');
const fs = require('node:fs');
const commands = [];
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
// Place your client and guild ids here
const clientId = '913559840780091453';
const guildId = '912552644462121050';
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
commands.push(command.data.toJSON());
}
const rest = new REST({ version: '9' }).setToken(token);
(async () => {
try {
console.log('Started refreshing application (/) commands.');
await rest.put(
Routes.applicationGuildCommands(clientId, guildId),
{ body: commands },
);
console.log('Successfully reloaded application (/) commands.');
} catch (error) {
console.error(error);
}
})();

From the error you are receiving, I can see that the data property apparently doesn't exist on the command object. Have you defined/exported it in the respective command file?
Try logging the command.data object to see if anything pops up. That's probably the error.

Replace
commands.push(command.data.toJSON());
with
commands.push(JSON.stringify(command.data));
Thanks to Vincent for helping!

Discord.js file error when activating multiple projects

I have a project and I plan to activate more than one bot in this project, but I encountered such a problem while activating my first bot.
Discord.js Version: 13.6.0
Node.js Version: v16.13.2
I leave the glitch project link.

This is because . matches to /app/botlar due to botlist2.js being executed in the file index.js. So for example you would need to do something like this:
fs.readdirSync('./botlar/botlist2/commands');

Discord.js client missing intents

I have 2 bots that I'm bringing back from deprecated, one works fine, the other one keeps giving me an error for client missing intents. Thing is I put the intents in there, like the other bot but it just won't work and I don't know why.
A helping hand please?
The bash:

ReferenceError: client isn't defined

I just started building new bot and whenever i try to use node . in the terminal I get error like this;
ReferenceError: client is not defined

at internal/main/run_main_module.js:17:47
Here is my whole code, i don't know where the problem could be;
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '+';
const fs = require('fs');
client.command = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for(const file of commandFiles){
const command = require(`./commands/${file}`);
client.command.set(command.name, command);
}
client.once('ready', () =>{
console.log('Bot is turned on');
}),
client.log('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.lenght).split(/ +/);
const command = args.shift().toLowerCase
if(command === 'bok'){
client.commands.get('ping').execute(message, args);
}
})
client.login('token');

Make sure to reinstall discord.js and try this code:
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '+';
const fs = require('fs');
client.command = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for(const file of commandFiles){
const command = require(`./commands/${file}`);
client.command.set(command.name, command);
}
client.on('ready', () =>{
console.log('Bot is turned on');
}),
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.lenght).split(/ +/);
const command = args.shift().toLowerCase
if(command === 'bok'){
client.command.get('ping').execute(message, args);
}
})
client.login('token');
