Be careful when using String#length, some unicode characters count for 2. Take "🔥" for example. Splitting this string in half will break the emoji.

WOW, includes() is almost perfect for conditionals in the game I'm making; if the word in question exists in the text prompt then I can use that as a flag instead of explicitly storing conditions elsewhere.

Thanks!

It's best practice to use 'const' instead of 'let', unless you plan on changing the value.
