Javascript 识别句子，无论句子中的任何位置大小写

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"

Answer 1

You can do:

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