Force an array to recalcuate length after sort
- by Rhyono
If you take an array and do the following:
arr = [];
arr[100] = 1;
The length will be 101, which makes sense due to 0-99 being set as undefined
Now if we sort that array: arr.sort() it will look like this: [1, undefined x100] since keys are not preserved. However, the length is still 101, since the undefined have all been moved to the end,…
