Normalize numeric literals

5

Prettier normalizes numeric literals, e.g. by removing unnecessarily trailing zeros but Rome doesn't.

Parenthesize expressions

1

Prettier uses an exhaustive heuristic of when it should insert parentheses or not. Rome should implement a similar heuristic. https://github.com/prettier/prettier/blob/6d02cd9650be29d1b11ab6ff1442eac4f5415c06/src/language-js/needs-parens.js#L20-L793 Relevant test cases with differences: * js/assignment/sequence.js * js/async/await-parse.js *...

Formatting long conditional expressions & types

11

Rome's formatter doesn't break long conditional expressions across multiple lines when they exceed the line width.
