/**
|
|
* Like `Array#splice`, but smarter for giant arrays.
|
|
*
|
|
* `Array#splice` takes all items to be inserted as individual argument which
|
|
* causes a stack overflow in V8 when trying to insert 100k items for instance.
|
|
*
|
|
* Otherwise, this does not return the removed items, and takes `items` as an
|
|
* array instead of rest parameters.
|
|
*
|
|
* @template {unknown} T
|
|
* Item type.
|
|
* @param {Array<T>} list
|
|
* List to operate on.
|
|
* @param {number} start
|
|
* Index to remove/insert at (can be negative).
|
|
* @param {number} remove
|
|
* Number of items to remove.
|
|
* @param {Array<T>} items
|
|
* Items to inject into `list`.
|
|
* @returns {undefined}
|
|
* Nothing.
