+#### Make `getPreferredQuote` public (#16567 by @sosukesuzuki)
+
+This change makes the internal `getPreferredQuote` function a part of the public API.
+
+In languages like JavaScript, both single quotes and double quotes can be used for string literals. Prettier determines the quote to enclose a string literal based on the number of quotes within the string and the value of the [`singleQuote`](https://prettier.io/docs/en/options#quotes) option. For more details, please refer to the [Rationale](https://prettier.io/docs/en/rationale.html#strings) page.
+
+The `getPreferredQuote` function determines the appropriate quote to enclose a string literal and has the following interface:
+
+```ts
+type Quote = '"' | "'";
+function getPreferredQuote(
+  text: string,
+  preferredQuoteOrPreferSingleQuote: Quote | boolean,
+): Quote;
+```
+
+Here are some examples of how to use it:
+
+<!-- prettier-ignore -->
+```jsx
+import * as prettier from "prettier";
+
+const SINGLE_QUOTE = `'`;
+const DOUBLE_QUOTE = `"`;
+
+console.log(prettier.util.getPreferredQuote(`Hello World Test`, SINGLE_QUOTE)); // '
+console.log(prettier.util.getPreferredQuote(`Hello World Test`, DOUBLE_QUOTE)); // "
+console.log(prettier.util.getPreferredQuote(`'Hello' "World" 'Test'`, SINGLE_QUOTE)); // "
+console.log(prettier.util.getPreferredQuote(`"Hello" 'World' "Test"`, DOUBLE_QUOTE)); // '
+console.log(prettier.util.getPreferredQuote(`"Hello" "World" "Test"`, SINGLE_QUOTE)); // '
+console.log(prettier.util.getPreferredQuote(`'Hello' 'World' 'Test'`, DOUBLE_QUOTE)); // "
+```
+
+Making this function public will benefit plugin developers. Since the function is relatively short, you can find more details in the [implementation](https://github.com/prettier/prettier/blob/509a0cc10f12cbfa5304737965f99284449aca88/src/utils/get-preferred-quote.js).
