How to make the bot conditionally send a message in lower case?

Question

JavaScript

Hello. Please help me, I need the bot to send a message according to the condition and not pay attention to the register. BUT be sure to look at the example, otherwise it's hard to explain.

FOR EXAMPLE:

message.content = message.content.lower()

if message.content in ['ghbdtn', 'ghbdtn!', 'ghbdtn)'] :
await message.channel.send(f'>>> **_{ message.author}_ wanted to say: ** Hello!')
await message.delete()

This is a sample code from Python. What is highlighted in bold I need to repeat in JavaScript.

const Discord = require('discord.js')
const client = new Discord.Client() 

client.on('ready', () =>{ 
    console.log(`Привет! ${client.user.tag} запустился!`) 
})

client.on("message", message => {
    if(message.content.toLowerCase()=="ping")
    {
    message.channel.send(message.author.tag + ", мой пинг равен " + client.ping)
    message.delete()
    }
})
client.on("message", message => {
    if(message.content.toLowerCase()=="pong")
    {
    message.channel.send(message.author.tag + ", мой понг не равен" + client.ping)
    message.delete()
    }
})


client.login(token)

Answer 1

client.on("message", message => {
    if(["one", "two", "three)"].indexOf(message.content.toLowerCase()) !== -1 )
    {
    message.channel.send("Привет!")
    message.delete()
    }
})

Answer 2

Array.includes() ?
