2. Go
Short introduction

3. Outline
• Story of Go
• Purpose of Go
• Solving modern programing challenges
• Who is using Go?
• Conclusion

4. Story of GO
Robert Griesemer Rob Pike
Ken Thompson
On 2007, started sketching the goals for a new language on the
white board
On 2009, became an open source project
On 2012, first stable release

5. Story of GO
‘’ In Google we have very large software systems and we spent
so long literally waiting for compilations’’
Rob Pike

6. Story of GO
‘’The three of us got together and decided that we hated C++’’
ken Thompson.

7. Purpose of GO
• Computers are enormously quicker but
software development is not faster.
• Dependency management
• Concurrency is Built In
• Memory Management

8. Solving Modern Programming
Challenges
• Choosing Static or Dynamic Language
• Programs Compile Quickly
• Easy Memory Management
• Enables Code Reuse
• How Will Your Language Handle Concurrency

9. Static or Dynamic Language
• Dynamic Languages
– Easy programing
– Not type safe
• Static Languages
– Type safety
– Slower

10. Go is Static language, but..
• Number := 5
• Name := “Mohammed”
• isTrue := false

12. In Go,
you wouldn't spend a second of
time compiling

13. Memory Management
• Applications may crash if there is :
– Improper memory management
– leak memory
• In languages, like C or C++, you need to allocate
a piece of memory before
you can use it, then de-allocate

14. Memory Management
Go
has a modern garbage collector
that does the hard work for you

15. Enables Code Reuse
Go
Rethinks traditional object orientation
for a flexible hierarchy-free type
system that enables code reuse with
minimal refactoring overhead.

16. Handle Concurrency
• Building a concurrent program is very hard
• You need to be careful from
– Race condition
– Dead Lock

17. Handle Concurrency
• Go provides :
– Goroutines
• Like threads, but use less memory and code
– Channels
• Communication way between goroutines

18. Who is using GO ?

19. Conclusion
• Go is a :
–compiled,
–concurrent,
–garbage-collected,
– statically typed language
–developed at Google.
– and, It is an open source project
