Writing a "Hello, World!" program

First things first: let's create a folder for our first program. You can do this directly from VSC or by using your favorite terminal. Since we have just set up our IDE to play with Bosque, I recommend that you use it. First, click File | New File. A new tab named Untitled-1 should appear—click File | Save (or press Ctrl + S on the keyboard) in order to rename it and save it at your desired location. Save the file under the name main.bsq. If you prefer to do this using a terminal, open it and type the following command:

$ mkdir first-project
$ cd first-project

Now, open VSC in the directory you have just created and create a file named main.bsq, as described earlier.

Once you have created the main.bsq file, fill it with the following content and save it:

namespace NSMain;
entrypoint function main(): String {
        return "Hello, world!";
}

I will explain this code...
