Remove last item from array
arrays, javascript, slice
Solution
Use splice(startPosition, deleteCount)
array.splice(-1)
var array = ['abc','def','ghi','123'];
var removed = array.splice(-1); //last item
console.log( 'array:', array );
console.log( 'removed:', removed );
Problem
I have the following array. ``` var arr = [1,0,2]; ``` I would like to remove the last element i.e. 2. I used `arr.slice(-1);` but it doesn't remove the value.
