FAQ

Which programming languages are supported?

Currently JavaScript, HTML, CSS, and Python are supported. More languages will be added based on user demand.

Will formatting change my code logic?

No, formatting only adjusts indentation and whitespace — it does not alter any code logic or functionality and is safe to use.

What is the difference between Tab and space indentation?

Tab width may vary across editors, while space indentation displays consistently. Choose based on your team convention.
