I learned from this script that you could access the array variable through:

const [a, b] = ['hello', 'world'];

similarly like:

const {a, b} = {a: 'hello', b: 'world'}

I love JavaScript so much <3

Sometime longerMessage could be Object, will print [Object object]. Maybe use JSON.stringify(longerMessage, null, 2)?
