What language would you use to build a new website today?

I just started building a new site. I'm using ASP.Net Core and serving static pages with Nginx.

I mean obviously I would use English or i18n integration for the display language.
Then for the Code Language, maybe Node.Js or Go, never worked with ASP.Net Core so can't differente.

I mean obviously I would use English English English

Well if there's an option i would always use my mother language,but if there isn't that option,i would pick english :/

For a modern lenguage use Laravel, it uses PHP and modern libraries to make your work look professional.
