The Go Playground is a web service that runs on
The service receives a Go program, compiles, links, and
runs the program inside a sandbox, then returns the output.
There are limitations to the programs that can be run in the playground:
The playground can use most of the standard library, with some exceptions.
The only communication a playground program has to the outside world
is by writing to standard output and standard error.
In the playground the time begins at 2009-11-10 23:00:00 UTC
(determining the sigificance of this date is an exercise for the reader).
This makes it easier to cache programs by giving them deterministic output.
There are also limits on execution time and on CPU and memory usage.
The playground uses the latest stable release of Go.
To find the precise version, run this program.
