Description:

When formatting code with deno fmt, it currently converts double quotes to single quotes in JSX (HTML in JS) components. This behavior differs from Prettier, which preserves double quotes in JSX if the singleQuotes option is set to true.

Example:

In Prettier, with singleQuotes: true, double quotes are preserved in JSX, as shown below:

import React from 'react';

const SimpleComponent = () => {
  return (
    <div className="app">
      Hello, React!
    </div>
  );
};

However, deno fmt changes the quotes in JSX attributes to single quotes:

import React from 'react';

const SimpleComponent = () => {
  return (
    <div className='app'>
      Hello, React!
    </div>
  );
};

Feature Request:

Could Deno provide an option to preserve or enforce double quotes specifically in JSX, similar to how Prettier handles this with singleQuotes: true?

This feature would help users maintain consistency with double quotes in JSX without affecting other parts of the code where single quotes might be preferred.
