Array Prototype Find Last Index Codemod

Introduction

This codemod transforms the usage of the Array.prototype.findLastIndex method to its more efficient counterpart, ensuring consistent coding practices and potentially reducing bundle size by leveraging built-in ES features instead of polyfills or outdated methods.

Before

const array = [1, 2, 3, 4, 5];

const lastIndex = array.findLastIndex(element => element === 3);

After

const array = [1, 2, 3, 4, 5];

const lastIndex = array.findLastIndex(element => element === 3);
