This workshop jumps through a lot of what is covered in the Go Tour. The exercises are new and match more along with the class content, and some pieces (like testing and APIs) are not covered in the Go Tour.

2. Make a friend!
• Where are you from?
• What do you do?
• What technical experience do
you have (coding or not)
• Why are you interested in Go?
• Do you want to be Gopher
friends forever?

3. Why I love Go

4. You are already a Gopher

15. Functions

16. Exercise
• Declare 2 integers, 2 strings, and 2 booleans
• One should be set to it’s zero value and one
should be initialized to whatever you want
• Print out those variables
• Write a function that prints out all of these variables

22. If Statements

23. If Statements

24. Exercise
• Write a function that imports the library “time” to check what time
it is now and print out if it falls inside the time of this conference,
the WIT Experience
• var day := time.Date(Year, Month, Day, Hour, Minute, Second,
Nanosecond, Timezone)
• var now := time.Now()
• in the Play environment, time is always set to:
2009-11-10 23:00:00 +0000 UTC m=+0.000000000
• Convert this into a while loop where the program continually
runs until it is WIT Experience time
