Callbaxx.js – A utility library to bring callbacks to synchronous code

In plain words

Callbaxx.js is a utility library that enables developers to use callbacks in synchronous code. Released in October 2018, it provides tools for JavaScript developers working with synchronous operations who need callback functionality. The library is hosted on GitHub and serves as a bridge between callback-based patterns and synchronous code execution, making it useful for developers who need flexible code patterns without async/await or promise dependencies.
