Lines 41 to 53 in 35861e9

	const setEmojiSelection = emoji => {
	let selectedEmojis = state.responses.selectedEmojis
	if (selectedEmojis.map(e => e.emojiId).includes(emoji.id)) {
	state.responses.selectedEmojis = selectedEmojis.filter(e => e.emojiId !== emoji.id)
	} else {
	const emojiElem = document.getElementById(emoji.id)
	const icon = emojiElem.childNodes[0].innerHTML
	selectedEmojis.push({
	emojiId: emoji.id,
	emojicon: icon
	})
	}
	}

I don't like this implementation. It's hard to read, and for some reason

selectedEmojis = selectedEmojis.filter(e => e.emojiId !== emoji.id)

doesn't work. There must be a more pure way of implementing this.
