// Edit your template here!
// The contents in {category} will be replaced by the category you select in the Stream Manager.
const template = `Hello viewers, I'm playing {category}!`

// For advanced users!
// You can generate your own dynamic messages by defining a javascript function called `genMessage`.
// (if genMessage is defined, then the template variable is ignored)
// It should take a {category} string as input and return a fully formed string.
// Below is a pretty complex example. Uncomment it and edit to your liking:
/*
function genMessage(category) {
    if (category === 'Pokémon Unite') {
        return `Pikachu I choose you! Playing ${category}!`
    }

    const now = new Date()
    switch (now.getDay()) {
        case 1:
            return `Got them Monday feels. Playing ${category}.`
        case 6:
            return `Woohoo it's Saturday! I'll be playing ${category} ;P`
        default:
            return `I don't usually stream today but I'll be making an exception for ${category}!`
    }
