@letuandat8386, I have added more language examples for you.

I don’t have code of other languages ​​for example c/c++,java,c#

You can list all languages using the Language & Versions endpoint. To use a language, you must use the id of the language with the Code Compiler endpoint.

Update: Javascript is a front-end language and therefore does not work on the backend. You can use NodeJS to run some Javascript code.
