In this article, Toptal Freelance Software Engineer Vuk Djapic takes you through the intriguing ideas of Elm and its upsides and downsides in genuine use.

Introduction to the Elm programming language

Elm programming language and the Elm framework. They are a typed functional programming approach to the frontend that is influencing other popular technologies in a somewhat disruptive way.

Use case of ELM ?

The case expression works by matching an expression to a pattern. When a match is found, it evaluates the expression to the right of -> and returns whatever value is produced. We saw a simple example of pattern matching in the Case Expression section.

Feature and Advantage of using ELM ?

Let’s get this clear first, working in Elm hasn’t been all bad. Here are some of my brief highlights:

  • Refactoring is a breeze due to the strict typing and compiled aspect
  • The compiler is very helpful to work with most of the time and helps point you in the right direction for the most part
  • Immutability and Uni-directional data flow is baked right in — think Redux
  • Functional design and currying make functional composition very nice to work with
  • Styling system based on modern CSS in JS approaches (see Styled-Components)
  • You mostly don’t need to write front end tests!
