There are few mistakes in your code
1st:
You are missing : here
{
id: 4,
text: "You are so tired that you fall asleep while exploring the castle and are killed by some terrible monster in your sleep.",
// : is missing after options
options [
{
text: "Restart",
nextText: -1
}
]
},
2nd:
It should be Object.assign and NOT
state = object.assign(state, option.setState)
function selectOption(option) {
const nextTextNodeId = option.nextText
// It should be Object.assign
state = object.assign(state, option.setState)
if (nextTextNodeId <= 0){
return startGame()
}
state = Object.assign(state, option.State)
showTextNode(nextTextNodeId)
}
You should add defer attribute while linking js file in html file in this case
<script defer src="game.js"></script>
This should fix the problem
