process-es6 bridges the gap between modern ES6 syntax and older Node.js versions. It's a polyfill for the process object, ensuring features like process.nextTick and environment variables (process.env) are available and behave consistently in environments that don't natively support them. This allows developers to write ES6 code utilizing process functionality without sacrificing compatibility in older Node.js environments during deployment or execution. Conveniently simplifies your development by handling different versions, allowing you to focus on building your application.
