discord.js command handling else if problem - discord.js

Question

I'm new to discord.js and I'm trying to make a really simple command with command handling.
The content of the bot.js file:
const Discord = require('discord.js');
const client = new Discord.Client();
const { prefix, token } = require("./config.json");
const fs = require("fs");
client.commands = 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);
}
client.once('ready', () => {
console.log('On!');})
client.on('message', async message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(/ +/);
const command = args.shift().toLowerCase();
if (!client.commands.has(command)) return;
try {
client.commands.get(command).execute(message, args);
} catch (error) {
console.error(error);
message.reply("Error");
}
The content of the lunedi1.js file:
const Discord = require('discord.js');
const fs = require("fs");
const client = new Discord.Client();
const { prefix, token } = require("../config.json");
module.exports = {
name: "lunedi1",
description: "Codici videolezioni, li puoi ottenere facendo '.<giorno> <ora>",
execute(message, args) {
if(message.content.startsWith(prefix + "lunedi1")){
return message.channel.send("Diritto, 1630027401")
}else if(message.content.startsWith(prefix + "lunedi2")){
return message.channel.send("Italiano, 959924441")
}else if(message.content.startsWith(prefix + "lunedi3")){
return message.channel.send("Italiano, 959924441")
}else if(message.content.startsWith(prefix + "lunedi4")){
return message.channel.send("Fisica LAB, 954071647" )
}else if(message.content.startsWith(prefix + "lunedi5")){

}else if(message.content.startsWith(prefix + "martedi6")){
return message.channel.send("Storia, 959924441")
}else if(message.content.startsWith(prefix + "mercoledi1")){
return message.channel.send("Grafica, 954902455")
}else if(message.content.startsWith(prefix + "mercoledi2")){
return message.channel.send("Italiano, 959924441")
}else if(message.content.startsWith(prefix + "mercoledi3")){

}else if(message.content.startsWith(prefix + "giovedi5")){
return message.channel.send("Scienze della Terra, 1632151557")
}else if(message.content.startsWith(prefix + "venerdi1")){
return message.channel.send("Fisica, 1752593012")
}else if(message.content.startsWith(prefix + "venerdi2")){

return message.channel.send("Scienze della Terra, 1632151557")
}else if(message.content.startsWith(prefix + "sabato4")){

}else if(message.content.startsWith(prefix + "sabato5")){
return message.channel.send("Matematica, 957066907")
}
},
};
As you can see it is really simple but when I want that when I do like ".martedi2" I don't get "Georgrafia, 951609580" but it only works with ".lunedi1", others don't work and like do other 30 commands will be rlly confusing. If you need more info I can give that. Thx to everyone that will help me :)

Answer 1

command name is lunedi1 thats why. other will not work because message content starting does not starts with other, you can use arguments to solve this problem
code:
const Discord = require('discord.js');
const client = new Discord.Client();
const { prefix, token } = require("../config.json");
module.exports = {
name: "info",
description: "Codici videolezioni, li puoi ottenere facendo '.<giorno> <ora>",
execute(message, args) {
if (!args[0]) return message.channel.send("please give name");
if (args[0] === "lunedi1") {
return message.channel.send("Diritto, 1630027401")
} else if (args[0] === "lunedi2") {
return message.channel.send("Italiano, 959924441")
} else {
return message.channel.send("?");
};
}
};
usage:
[Prefix]info
example:
!info lunedi1
you can do this for other.
