Function Example

example_test.go:22–112

This example shows how to navigate to a http://play.golang.org page, input a short program, run it, and inspect its output. If you want to actually run this example: 1. Ensure the file paths at the top of the function are correct. 2. Remove the word "Example" from the comment at the bottom of the
