Go Programming Language - Learning The Go Lang way
Download as PPT, PDF2 likes858 views
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.
Go Programming Language - Learning The Go Lang way
- 1. The Go Way Navneet Karnani Mandrake Technologies
- 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
- 24. Completeness - Smart suggestions / errors - Code formatting - Dependency management - Build Tool - Testing framework - Performance measurement
