Not checking anything before or after the string "welcome"

Question

So I'm trying to have javascript match only the string "welcome" with a message containing that however I don't want it to only react when someone says "welcome" exactly. I think I have to use regex for this but I'm not sure and I've been pretty confused on it.

    if (message.content.toLowerCase() == 'welcome') {
     message.react(reactEmoji)
    }

Theres my code. I've tried a few different versions of regex like "/welcome/i" however that did not work

I want something like the image below to get reacted on like this 1

It does not answer my question. https://i.imgur.com/HOrNJnN.png These still do not get reacted on — Kevin D, Nov 14 '21 at 23:21
You could always keep it simple; ```if (message.content.toLowerCase().indexOf("welcome") > -1) {```. — Alain Doe, Nov 14 '21 at 23:46
Use `String#includes(x)` rather than `String#indexOf(x) > -1` since it's shorter syntax — MrMythical, Nov 15 '21 at 01:26

Get the lowercase version of it and run String#includes() on it.

if (message.content.toLowerCase().includes('welcome')) {
    message.react(reactEmoji)
}

Or you can use regex

if (/welcome/i.test(message.content)) {
    message.react(reactEmoji)
}
