C# also moves to cross-platform and mobile-based applications with the growth of .NET 8 and MAUI.
JavaScript is everywhere, from the front end (React, Vue, Angular) to the back end (Node.js). It is essential for full-stack developers, too. Startups, companies like SaaS, and product-based businesses have high recommendations for JavaScript. So, in this part, we can say JavaScript is the winner for its job diversity, and C# is a winner in company and backend development.
