Another reason for its popularity is the fact that is very beginner-friendly. It is a programming language that is functionally reactive for the purpose of developing front-end. Many developers have found out that choosing ELM for their project has helped them maintain a constant velocity all throughout the course of development. There are two main factors that make ELM stand out from the other serverless stacks. Firstly, ELM narrows down the path of programming which thereby leads to much maintainable code. Secondly, debugging is not at all a concern, as there are no exceptions during runtime.
