Javascript version of list.pop
are you looking for something like this? maybe you can modify it so that the pop function returns the removed element.
const arr1 = [10,20,30,40,50,60];
const arr2 = [10,20,30,40,50,60];
const arr3 = [10,20,30,40,50,60];
function pop(arr, idx) {
removedEl = arr.splice(idx,1)[0];
console.log('removed element: ',removedEl)
console.log('final array: ',arr);
}
pop(arr1,0);
pop(arr2,2);
pop(arr3,5)
