Utility Library for Building Web Applications in TypeScript Language

The dynamic weak typing nature of JavaScript (JS) allows for great flexibility, which helps web developers to become productive reasonably quickly. JS simply allows building software fast. It can be great for prototyping and small web project development. Unfortunately, in large scale web development, it comes at a cost. Weakly typed JS is error-prone and hard to scale. We will consider TypeScript (TS) as an alternative for JS. It is a strongly typed superset of JS. We will discuss its numerous advantages over JS for web development. Another problem for modern web application development is a traditional imperative approach in writing code. It is bulky and often ad-hoc. Therefore, such an approach is also hard to scale. We believe it is where the Functional programming (FP) approach can help a lot. We will briefly consider the formal foundation for modern FP and what are some of the advantages of using the FP approach. We also believe that combining the strongly typed nature of TS with the FP paradigm can yield tremendous results for web app development. We will finalize the paper by discussing the implementation of the open-source utility library in TS based on a statically typed functional programming approach. It aims to assist web developers in creating robust, composable web apps.
