Overview

The isSameDialect function checks whether multiple BCP‑47 locale codes represent the same dialect without requiring a GT class instance.

Reference

Parameters

Returns

boolean - true if all locale codes denote the same dialect

Examples

import { isSameDialect } from 'generaltranslation';

// Same dialect checks
console.log(isSameDialect('en-US', 'en-US')); // true
console.log(isSameDialect('en', 'en-US')); // true (base language matches regional variant)
console.log(isSameDialect('en-US', 'en-GB')); // false (different regions/variants)
console.log(isSameDialect('en-US', 'es-ES')); // false (different languages)

Notes

• Treats base languages as parents of regional variants
• Regional variants must match exactly
• Essential for locale fallback logic
• Accepts flexible input formats
• No external dependencies

Next steps

• Use the GT class method isSameDialect
• Compare languages with isSameLanguage
