// …

nextEvents = push(nextEvents, [
  ['enter', events[open][1], context],
  ['exit', events[open][1], context]
])

// …

splice(events, open - 1, index - open + 3, nextEvents)

// …

API

This module exports the following identifiers: push, splice. There is no default export.

push(list, items)

Append items (an array) at the end of list (another array). When list was empty, returns items instead.

This prevents a potentially expensive operation when list is empty, and adds items in batches to prevent V8 from hanging.

Parameters

• list (unknown[]) — List to operate on
• items (unknown[]) — Items to add to list

Returns

list or items

splice(list, start, remove, items)

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.

Parameters

• list (unknown[]) — List to operate on
• start (number) — Index to remove/insert at (can be negative)
• remove (number) — Number of items to remove
• items (unknown[]) — Items to inject into list

Returns

void
