What is Wavel.ai?

The multilingual redirect JavaScript code sets the URL of an element with the ID 'language-link' based on the current subdomain of the website. It matches the subdomain with language codes to redirect the user to a language-specific URL. If no match is found, it redirects to English by default. This mechanism supports many languages, including, but not limited to, English, Spanish, German, French, Portuguese, Polish, Italian, Chinese, Turkish, Russian, Dutch, Japanese, and Arabic.
