Language comparison
Key differences between TypeScript and Gleam
| Characteristic | TypeScript | Gleam |
|---|---|---|
| Syntax | C-like syntax, similar to JavaScript with added type annotations. | Clean, ML-inspired syntax, similar to Elm or OCaml. |
| Paradigm | Multi-paradigm; primarily object-oriented and functional. | Purely functional. |
| Typing | Static, structural, optionally strict, gradual typing. | Static, strong, and strict typing with type inference. |
| Performance | Runs on JavaScript engines; performance depends on JS runtime. | Compiles to Erlang or JavaScript; inherits performance characteristics of the BEAM or JS. |
| Libraries and frameworks | Extensive ecosystem; can use all JavaScript libraries and frameworks. | Smaller ecosystem; can use Erlang/Elixir libraries, but fewer native Gleam libraries. |
| Community and support | Large, active community with strong support from Microsoft and open source contributors. | Small but growing community; mostly community-driven support. |
| Learning curve | Gentle for JavaScript developers; steeper for those new to static typing. | Moderate; easier for those familiar with functional programming, but new concepts for others. |
Common questions
Frequently Asked Questions
How do I convert TypeScript to Gleam?
Paste your TypeScript code into the input box, confirm the languages are set to TypeScript and Gleam, and click Convert. CodeConvert AI analyzes your TypeScript code and generates equivalent Gleam code in seconds, preserving the original logic and structure.
What are the main differences between TypeScript and Gleam?
TypeScript and Gleam differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each TypeScript construct to its closest Gleam equivalent. See the comparison table below for the key differences between TypeScript and Gleam.
Is the converted Gleam code accurate?
The AI produces high-quality Gleam code that preserves the behavior of your original TypeScript code and follows Gleam conventions. It handles common patterns, data structures, and idioms for both TypeScript and Gleam. For large or performance-critical code, review and test the Gleam output before using it in production.
Can I convert an entire TypeScript project to Gleam?
You can convert TypeScript 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 TypeScript to Gleam. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Gleam back to TypeScript?
Yes. CodeConvert AI converts in both directions, so you can convert Gleam to TypeScript just as easily using our Gleam to TypeScript converter. Try the Gleam to TypeScript Converter
