Answers for "js destrcture first last element"

js remove first and last element from array

a = [1,2,3,4]
b = a.slice(1,-1);

javascript move last array element to first

let arr1 = [1, 2, 3, 4, 5]
let arr2 = [1, 2, 3, 4 ,5]
// first to the last
arr1.push(arr1.shift()) // [2, 3, 4, 5, 1]

// last to the first
arr2.unshift(arr2.pop()) // [5, 1, 2, 3, 4]
