remove-array-items
remove items from a javascript array without generating memory garbage.
Despite there being a number of "remove array items" in npm, I couldn't find satisfying all criteria:
- doesn't generate garbage
- performs similar or better to the native
array.splice - has tests
- es3+ compatible
so here we are.
originally inspired by https://gamealchemist.wordpress.com/2013/05/01/lets-get-those-javascript-arrays-to-work-fast/
(which is a gold mine for performant, non-garbage generating array operations by the way.)
api
removeItems(arr, startIdx, removeCount)
usage
const removeItems = require('remove-array-items')
const arr = [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
removeItems(arr, 3, 4) // after running, arr === [ 1, 2, 3, 8, 9 ]
