Language comparison
Key differences between Gleam and TypeScript
| Characteristic | Gleam | TypeScript |
|---|---|---|
| Syntax | Clean, concise, inspired by ML-family languages (like OCaml and Elm), uses significant whitespace, and has a functional style. | Superset of JavaScript, uses C-style syntax with braces and semicolons, familiar to JavaScript and C-family language users. |
| Paradigm | Purely functional, emphasizes immutability and pattern matching. | Multi-paradigm; supports object-oriented, functional, and procedural programming. |
| Typing | Statically typed with strong, inferred types and no null or undefined values. | Statically typed (with type inference), but allows gradual typing and can interoperate with untyped JavaScript. |
| Performance | Compiles to efficient Erlang or JavaScript code, optimized for BEAM (Erlang VM) performance. | Compiles to JavaScript, so runtime performance is the same as JavaScript. |
| Libraries and frameworks | Limited ecosystem, mainly focused on BEAM and functional programming; fewer libraries and frameworks. | Vast ecosystem, can use any JavaScript library or framework (React, Angular, Vue, etc.). |
| Community and support | Small but growing community, limited resources and support compared to mainstream languages. | Large, active community with extensive documentation, resources, and support from Microsoft. |
| Learning curve | Steeper for those unfamiliar with functional programming or ML-style languages. | Gentle for JavaScript developers; easier for those with experience in C-family languages. |
Common questions
Frequently Asked Questions
How do I convert Gleam to TypeScript?
Paste your Gleam code into the input box, confirm the languages are set to Gleam and TypeScript, and click Convert. CodeConvert AI analyzes your Gleam code and generates equivalent TypeScript code in seconds, preserving the original logic and structure.
What are the main differences between Gleam and TypeScript?
Gleam and TypeScript differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Gleam construct to its closest TypeScript equivalent. See the comparison table below for the key differences between Gleam and TypeScript.
Is the converted TypeScript code accurate?
The AI produces high-quality TypeScript code that preserves the behavior of your original Gleam code and follows TypeScript conventions. It handles common patterns, data structures, and idioms for both Gleam and TypeScript. For large or performance-critical code, review and test the TypeScript output before using it in production.
Can I convert an entire Gleam project to TypeScript?
You can convert Gleam 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 Gleam to TypeScript. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert TypeScript back to Gleam?
Yes. CodeConvert AI converts in both directions, so you can convert TypeScript to Gleam just as easily using our TypeScript to Gleam converter. Try the TypeScript to Gleam Converter
