🤖
Picking your first language is a big decision — here's why C# is a great one. 🎯

There are many programming languages — so why is it worth learning C# specifically? For one, C# is incredibly versatile: with the .NET platform behind it, the exact same language can build a website, a phone app, a desktop program, and a video game.

🤖
Video games are a huge draw for a lot of people learning C#. 🎮

One especially popular reason people learn C#: it is the main scripting language for Unity, one of the most widely used game engines in the world. If you dream of making your own games, C# is often the very first language you'll need.
