Split Lines Codemod

Introduction

This codemod replaces the usage of the split-lines npm module with native JavaScript string methods. The goal is to eliminate an unnecessary dependency, optimize the codebase, and enhance performance by utilizing built-in ES features.

Before

import splitLines from 'split-lines';

const lines = splitLines(someString, { preserveNewlines: true });

After

const lines = someString.split(/(\r?\n)/).reduce((acc, part, index, array) => {
    if (index % 2 === 0) {
        acc.push(part + (array[index + 1] || ''));
    }
    return acc;
}, []);
