Frequently asked questions
Is my code uploaded to a server?
No. Everything is processed with JavaScript directly in your browser.
What indentation width should I use?
It depends on the language and your team's style: 2 spaces is common in JavaScript/TypeScript, 4 in Python and Java.
Does it respect the rest of the code, not just the indentation?
Yes, it only modifies the tabs or spaces at the start of each line (the indentation), the rest of the content stays intact.
