Lesson 1 / 68
Getting Started
To run Go you will need the following. Go was developed by Google to combine a deliberately simple syntax with fast execution, and it is widely used for the backends of large web services and for cloud infrastructure tooling.
- Go itself: install it from the official site (go.dev).
- An editor: Visual Studio Code with the Go extension is the standard choice.
Once installed, go run yourfile.go runs your program straight away (this single command handles both compiling and running).
