What is Elm?
Elm is a programming language that you can use to build web apps. Elm is user-friendly, which makes it a great place to learn to build web apps. Elm is a functional language that compiles to JavaScript. It is a separate language from JavaScript, which means you must learn the syntax and language rules of Elm.
What are the advantages of Elm?
- Elm allows you to write well-architectured code that is easy to read.
- Elm makes front-end development simpler.
- Elm provides light operations, which means it involves less fatigue than JavaScript. With JavaScript-heavy apps, a lot of tooling and frameworks can be required to make a simple app. Elm provides a lighter operation by being self-contained.
- Elm comes with creative built-in tools, meaning you don't have to download other packages
- Elm is easy to understand and use once you learn the language
- Elm has no runtime exceptions, which can occur in JavaScript. Instead, Elm gives you warning messages.
- Elm's warning messages are in readable language
- Elm's built-in package manager protects code from minor errors
