Javascript recognize sentence regardless of upper and lower case anywhere in the sentence

Question

    bot.on('message', message => {

        if (message.content === 'This is a test') {
           message.channel.send("Hello!");

        }
});

So I want the bot to recognize the sentence even if it is spelled something like this: "THIs iS A tEsT"

Just compare either lower or uppercases of both. To detect it anywhere in the sentence use `indexOf`. `message.content.toLowerCase().indexOf('this is a test') !== -1` — Lain, Jun 19 '20 at 21:18

You can do:

if (message.content.toLowerCase().includes('this is a test')) {
           message.channel.send("Hello!");
        }
