Nice college level ppt about GOOGLE GO

1. Google GO (The
Programming Language)
By-Ajay Singh
Computer Science(8th Sem)

2. HISTORY
 Made by Rob Pike and Ken Thompson in 2008
 Officially launched in 2012
 GO 1.0 was the first version.
 Recently GO 1.2 was launched on 1st Dec 2013.
 Born out of a need for Ease of Programming combined with Type safety &
Portability

3. BRIEF OVERVIEW
 Open Source Language driven by a large Community
 Suitable for Modern Systems and Large Scale programming
 Go aims to combine the safety & performance of Statically typed compiled
language with expressiveness & convenience of Dynamically typed interpreted
language
 Extension of file is .go (e.g- HelloWorld.go)

4. FEATURES Of GO
 Easy to Learn
 No Exception Handling
 Compilation is Very Fast
 No classes(Go is a Procedural
Language)
 Deployment is Easy
 Easy Concurrency via Channels
 Uses Garbage Collection
 Uses Interfaces
 Functions have multiple return
statements
 No overloading
 No inheritance but embedding
 No constructors only simple
functions

5. SYNTAX OVERVIEW
 Looks similar to C Language
 End of line semicolon are
Optional
 Variable declaration is
Optional
 Variable name is followed by
its type
 Variables can also be
declared by initialization

6.  Visibility of functions is
controlled using
Capitalization
 If First letter of Function
name is CAPITAL then it is
publically available outside
the package
 If First letter of function
name is small then it will be
private

7. HelloWorld.go

8. Set Of STANDARD TYPES

9. Modern Standard Library & Frameworks
Standard Library(Packages)
Frameworks
 Json,xml
 Revel
 net./http
 Gorilla
 Text/template and html/template
 Web.go
 Time
 IO formatting
 Images
 And many more….

10. GO TOOLS!(Commands)
 Go run hello.go [execution of program]
 Go test [runs unit testing]
 Go install [install local packages]
 Go get [install external packages]
 Go fmt [format the sources]
 Go doc [source documentation]

11. USERS of GO
 Google
 Heroku
 Mozilla
 Cloudfare
 Canonical
 Bit.ly

12. CONCURRENCY
 It talks about composition of independently executing processes
 It is done with the help of Goroutines and Channels
 Goroutine: is a light weighted function which behaves like a thread
 Channel: helps in Synchronization and Communication between Goroutines
 Upto thousands of Goroutines can execute simultaneously

13. Future Of GO
 GO 1.2 was launched recently in Dec 2013
 Currently Google is focusing on increasing the performance
 Fixing of Bugs related to Garbage Collection and Bootstrapping is being done
 GO 2.0 has not been started yet

14. Conclusion
 Go has nothing cool/special
 But it is a nice language
 Easy to Learn
 That will make you more Productive
 And it is well suited to Real World Problems
