        # TypeScript runtime comparisons

Comparison of Node.js TypeScript runtimes.

> **Disclaimer:** This comparison is by the author & maintainer of [tsx]

## Compared runtimes

- [tsx]

- [@swc/register]

- [esbuild-runner]

- [jiti]

- [sucrase]

- [ts-node]

- [tsm]

## Methodology

- Tested on Node.js v12.20.0 because they all support it, and the `node:` prefix is not supported in `require()`

- Tested in both [package types](https://nodejs.org/api/packages.html#type) `commonjs` & `module` when applicable
