In this article, I share with you the journey and the struggles of turning a large, monolithic JavaScript mathematics library, mathjs, into a modular one embracing ES6 modules and functional programming. Because of the heavily intertwined nature of the functionality this was a huge and unique challenge. Why? Math.js is a popular JavaScript library that brings advanced mathematics to the web browser and server. The unique value of math.js lies in offering an integrated solution to work with different types of data like complex numbers and matrices, and offering a math-friendly syntax that allows expressing mathematics in a readable, intuitive way.

tl;dr Math.js v2 has been released a week ago. It has a completely reworked, modular architecture which allows creating custom builds. All functions have been rewritten into typed-functions. This takes away a lot of overhead for type checking and type conversions. These changes create a lot of flexibility in both extending and consuming the library. A week ago math.js v2 has been released, a big milestone! You can download it here. Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, fractions, big numbers, complex numbers, units, and matrices. It has been around for two and a half years now and has a steadily growing community around it and number of dedicated contributors.
