Language comparison
Key differences between Erlang and Haskell
| Characteristic | Erlang | Haskell |
|---|---|---|
| Syntax | Erlang has a syntax that is similar to Prolog and uses pattern matching extensively. | Haskell has a syntax that is based on mathematical notation and is known for its strong type system. |
| Paradigm | Erlang is a concurrent, functional programming language. | Haskell is a purely functional programming language. |
| Typing | Erlang has dynamic typing. | Haskell has static typing. |
| Performance | Erlang is designed for high concurrency and fault-tolerance. | Haskell is known for its focus on correctness and expressiveness rather than raw performance. |
| Libraries and frameworks | Erlang has a rich set of libraries and frameworks for building distributed and fault-tolerant systems. | Haskell has a growing ecosystem of libraries and frameworks, but it may not have as many options as more mainstream languages. |
| Community and support | Erlang has an active community and good support from the language creators. | Haskell has a passionate community, but it may not have as much commercial support as more mainstream languages. |
| Learning curve | Erlang has a moderate learning curve, especially for developers who are new to functional programming. | Haskell has a steep learning curve, especially for developers who are new to functional programming. |
Common questions
Frequently Asked Questions
How do I convert Erlang to Haskell?
Paste your Erlang code into the input box, confirm the languages are set to Erlang and Haskell, and click Convert. CodeConvert AI analyzes your Erlang code and generates equivalent Haskell code in seconds, preserving the original logic and structure.
What are the main differences between Erlang and Haskell?
Erlang and Haskell differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Erlang construct to its closest Haskell equivalent. See the comparison table below for the key differences between Erlang and Haskell.
Is the converted Haskell code accurate?
The AI produces high-quality Haskell code that preserves the behavior of your original Erlang code and follows Haskell conventions. It handles common patterns, data structures, and idioms for both Erlang and Haskell. For large or performance-critical code, review and test the Haskell output before using it in production.
Can I convert an entire Erlang project to Haskell?
You can convert Erlang files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Erlang to Haskell. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Haskell back to Erlang?
Yes. CodeConvert AI converts in both directions, so you can convert Haskell to Erlang just as easily using our Haskell to Erlang converter. Try the Haskell to Erlang Converter
Is the Erlang to Haskell converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Erlang to Haskell without an account for up to 2 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
