destructuring arrays with rest operator

Comment

// Rest operator on Arrays;
// It's usually shown as ...rest
// but you can name this what you like
// Think of it as "get the ...rest of the array"
const [q, r, ...callThisAnythingYouWant] = [1, 2, 3, 4, 5, 6, 7, 8];

console.log(q, r); // 1 2
console.log(callThisAnythingYouWant); // [ 3, 4, 5, 6, 7, 8 ]
