Input code:

function someFn(
	// comment a
	a,
    // comment b
    b,
) {}

Fixed code:

const someFn = (a, b) => {};

Suggested Solution

Preserve whitespace and comments

It looks like getSourceCode() used to rewrite the function body is now deprecated and instead context.sourceCode should be used. Here is some documentation on how eslint API handles comments: https://eslint.org/docs/latest/extend/custom-rules#accessing-the-source-text

In case you're interested, I ended up rolling my own solution which makes autofixes with more precision: https://github.com/privatenumber/lintroll/tree/develop/src/custom-rules/prefer-arrow-functions
