This looks very clunky if it's a demo with previewable code blocks!

Thanks for reporting. Your particular example is the logic that handles the Mitosis compile-away component For, which is different for each generator. I can show you the .join('\n') in the case of the React generator (which also runs for React Native):

mitosis/packages/core/src/generators/react/blocks.ts

Line 88 in 4038116

.join('\n')}${wrap ? closeFrag(options) : ''}

removing the newline here should fix the issue for React.

If you want to fix this for all generators, you will have to go to each generator individually and replace the newlines with empty strings.
