Javascript: Efficiently move items in and out of a fixed-size array

QUESTION

Javascript: Efficiently move items in and out of a fixed-size array

Asked 2018-Jan-15 at 00:29

If I have an array that I want to be of fixed size N for the purpose of caching the most recent of N items, then once limit N is reached, I'll have to get rid of the oldest item while adding the newest item.

Note: I don't care if the newest item is at the beginning or end of the array, just as long as the items get removed in the order that they are added.

The obvious ways are either:

push() and shift() (so that cache[0] contains the oldest item), or
unshift() and pop() (so that cache[0] contains the newest item)

Basic idea:

You could use Array#copyWithin.

The copyWithin() method shallow copies part of an array to another location in the same array and returns it, without modifying its size.

Description

The copyWithin works like C and C++'s memmove, and is a high-performance method to shift the data of an Array. This especially applies to the TypedArray method of the same name. The sequence is copied and pasted as one operation; pasted sequence will have the copied values even when the copy and paste region overlap.

The copyWithin function is intentionally generic, it does not require that its this value be an Array object.

The copyWithin method is a mutable method. It does not alter the length of this, but will change its content and create new properties if necessary.
