i doo not now how to get there
What is your coding background? What do you mean by “game”? Do you mean a simple little game or some complex, graphics intensive grand game?
In any case, if you look on youtube, you will find examples of people coding simple games.
Well, that’s a good start for learning some basic coding. You can make some simple browser based games with that. And learn some basic coding skills. But if you mean a video game that runs as an app on the computer, then you would probably be using some other language, like C, C++, C# with Unity, etc. There is a whole ecosystem of languages, libraries, and frameworks. And of course there are mobile games, so that would be Java/Kotlin or Objective-C/Swift or a library like React Native. I would google “how to become a videogame developer” and read what you find. There is probably more than one path - but any of them will be moving you in the right direction.
I used to make games 2d in unity with c# and c++, for simple games most you need to know is logic operators(if, while, case), two channel that help a lot in start:
