What is the optimal method for eliminating a singular item from a substantial array in JavaScript?

A website built with Vue.js fetches a variety of objects from an API and stores them in an array. Users can view this data in a table and delete individual items if needed. The array typically contains 700-2000 objects, but could potentially have anywhere from 0 to tens of thousands (although unlikely). My query is: What method would provide the best performance for removing an element from this array?

We are currently using the splice() method, which we believe may not be the most efficient since users often delete items at the start of the array, resulting in re-indexing of the entire array.

Would reversing the array before and after splicing offer better efficiency? Alternatively, should we consider utilizing the filter() method or looping through the array with a for/while-loop to create a new array excluding the deleted element?

Answer №1

Through experimentation with mock data, I discovered that the splice method takes approximately 1 millisecond when applied to an array containing 2000 elements. The issue lies in my implementation of Vuex store, leading to significant delays.
