Golang from Scratch
Getting Started with Hello World in Go
We'll cover a small Golang program that prints a string to the terminal, showing how to set up an executable program, import a package, and build a binary.
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.
