Array.prototype.concat Codemod

Introduction

This codemod optimizes the usage of the Array.prototype.concat method by transforming its usage into a more efficient syntax. This helps to reduce redundancy and improve performance within the codebase.

Before

const array1 = [1, 2, 3];
const array2 = [4, 5, 6];
const combined = array1.concat(array2);

After

const array1 = [1, 2, 3];
const array2 = [4, 5, 6];
const combined = [...array1, ...array2];
