Frequently asked questions

What is a .tsx file?

Source code combining TypeScript or JavaScript with JSX syntax, used to build React user interface components.

Can I edit a .tsx file?

Yes — .tsx files are commonly editable with software such as Visual Studio Code.

Does having a .tsx extension mean the file is safe?

No single extension can guarantee that. Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur. Always consider where the file came from, not just its name.
