String.prototype.at Codemod

Introduction

This codemod replaces the usage of the string.prototype.at method with a more performant implementation. It updates any instance of at() in string operations to ensure better compatibility and efficiency within the codebase.

Before

const myString = "Hello, World!";
const character = myString.at(1); // returns 'e'

After

const myString = "Hello, World!";
const character = myString[1]; // returns 'e'
