The document summarizes a presentation on the Go programming language. It covers the basics of Go including that it is open source, has no semicolons, uses namespaces and the "main" keyword. It then walks through examples of printing multiplication tables, using arrays and slices, testing code, concurrency using goroutines and channels, working with structs and interfaces. The presentation highlights Go's simplicity, reliability and efficiency and provides a GitHub link for the example code.

2. Prerequisites
- Audience is smart and understands programming
- Ability to use Google
- Audience is looking for takeaways to be things not
found on blogs

3. Scope
- Talk about the behavior
- Look at and discuss code
- Keep use cases simple to keep focus
- Cover the basics to enable building on the
knowledge
- Promo: Talk on Web App development using Go
later in the Conference

4. What is the charter of Go
Go is an open source programming
language that makes it
easy to build
simple, reliable,
and efficient software.

5. Hello world

6. Findings
- No semicolons
- Name space
- “main”

7. Multiply
Write an application to print multiplication tables
Hands On

8. STEP 1 – compute and print

9. Findings
- No type declarations

10. STEP 2 – use arrays

11. Findings
- Arrays are data types with a specified type and
size

12. STEP 3 – use slices

13. Findings
- Views into the array

14. STEP 4 – test

15. Findings
- Test infrastructure built in
- Building blocks work with Example and Standard
Conditionals
- Benchmarking

16. STEP 5 – concurrency

17. Findings
- Spawning “tasks” is a first class citizen
- Uses OS concept of “channels” for data exchange

18. STEP 6 – MAP, References … and
memory

19. Findings
- Go treatment of Local variables differs from other
languages
- Memory allocation uses the “make” method
- There is no “delete” needed

20. STEP 6 – Struct

21. Findings
- Structs are memory structures with optional
associated functions and methods

22. STEP 7 – inteRface

23. Findings
- Duck Typing

24. Completeness
- Smart suggestions / errors
- Code formatting
- Dependency management
- Build Tool
- Testing framework
- Performance measurement
