It has a struct `RGBA` defining this method. So for example to define green we can say: `color.RGBA{0x00, 0xFF, 0x00, 0xFF}` R G B A respectively. - -Packaging doing stuff with networking are grouped under `net`, e.g `net/http` - -Using `io.Copy` we can copy output from a reader to a writer. This way we can for example copy a HTTP response directly to stdout instead of buffering the entire output first. - -`strings.HasPrefix` exists - -To get a time delta we can use `time.Since` which returns a `time.Time`. We can just call for example `Seconds()` on that to get the elapsed seconds. - -Goroutines run concurrently and communicate over channels, they are started with the `go` keyword. Sending or receiving on a channel block the goroutine.
