 * **Fully typed:** Written in TypeScript, fully typed, API checked with <a href="https://api-extractor.com" target="_blank">_api-extractor_</a>, <a href="https://github.com/microsoft/tsdoc" target="_blank">_TSDoc_</a> documented
 * **Source maps lookup:** Shows exact position also in TypeScript code (compile-to-JS), one click to IDE position
 * **Stack trace:** Callsites through native <a href="https://v8.dev/docs/stack-trace-api" target="_blank">_V8 stack trace API_</a>, excludes internal entries
+* **Tree shake suport** via esm import syntax ([tree-shaking](https://webpack.js.org/guides/tree-shaking/))
 * **Pretty Error:** Errors and stack traces printed in a structured way and fully accessible through _JSON_ (e.g. external Log services)
 * **Code frame:** `tslog` captures and displays the source code that lead to an error, making it easier to debug
 * **Object/JSON highlighting:** Nicely prints out an object using native Node.js `utils.inspect` method
