Free JavaScript to Haskell Converter
How to use this tool?
This free online converter lets you convert code from JavaScript to Haskell in a click of a button. To use this converter, take the following steps -
- Type or paste your JavaScript code in the input box.
- Click the convert button.
- The resulting Haskell code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from JavaScript to Haskell using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.
JavaScript
Haskell
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between JavaScript and Haskell
| Characteristic | JavaScript | Haskell |
|---|---|---|
| Syntax | JavaScript has a C-like syntax with curly braces and semicolons. | Haskell has a unique syntax that is based on mathematical notation and is more declarative. |
| Paradigm | JavaScript supports multiple paradigms including object-oriented, imperative, and functional programming. | Haskell is a purely functional programming language. |
| Typing | JavaScript is dynamically typed. | Haskell is statically typed. |
| Performance | JavaScript is generally considered to have good performance. | Haskell is known for its focus on correctness and expressiveness rather than performance. |
| Libraries and frameworks | JavaScript has a wide range of libraries and frameworks available, making it suitable for various purposes. | Haskell has a smaller ecosystem of libraries and frameworks compared to JavaScript, but it still has a decent collection. |
| Community and support | JavaScript has a large and active community with extensive support resources. | Haskell has a smaller but dedicated community with active support channels. |
| Learning curve | JavaScript has a relatively low learning curve, especially for beginners. | Haskell has a steeper learning curve due to its unique concepts and functional programming paradigm. |
Frequently Asked Questions
How do I convert JavaScript to Haskell?
Paste your JavaScript code into the input box, confirm the languages are set to JavaScript and Haskell, and click Convert. CodeConvert AI analyzes your JavaScript code and generates equivalent Haskell code in seconds, preserving the original logic and structure.
What are the main differences between JavaScript and Haskell?
JavaScript 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 JavaScript construct to its closest Haskell equivalent. See the comparison table below for the key differences between JavaScript and Haskell.
Is the converted Haskell code accurate?
The AI produces high-quality Haskell code that preserves the behavior of your original JavaScript code and follows Haskell conventions. It handles common patterns, data structures, and idioms for both JavaScript and Haskell. For large or performance-critical code, review and test the Haskell output before using it in production.
Can I convert an entire JavaScript project to Haskell?
You can convert JavaScript 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 JavaScript 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 JavaScript?
Yes. CodeConvert AI converts in both directions, so you can convert Haskell to JavaScript just as easily using our Haskell to JavaScript converter. Try the Haskell to JavaScript Converter
Is the JavaScript 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 JavaScript to Haskell without an account for up to 5 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.
