    Instructor: 00:00 For our first Go program, we have a single file called main.go. Inside of main.go, we declare the package to be Main. This is the default for all executables. We import format because we're going to be printing a string later and we define a Main func. This is the function that will be called when we execute our executable.

    00:18 Finally, from the format package that we imported, we call print line with "Hello World." We can use Go Run to run our program. Also, since Go is a compiled language, we can run Go Build to build an executable. Now we have an additional file called Main, and when we run it, our program prints.
