$ ./build.jai - <path>

The compiler will then generate a binary in the bin directory.

For pong that would be:

$ ./build.jai - pong

The compiler will generate a binary named pong in the bin directory.

$ ./build.jai - <path> run

You can then pass the arguments you want to give to the executable after the run argument.
For example: ./build.jai - run foo bar baz.

For pong that would be:

$ ./build.jai - pong run
