Golang is a simple language to learn that is the opposite of Perl in certain senses like having strict predefined type declarations. It does not have features like implicit type conversions, classes, or pointer arithmetic for simplicity. However, it has implicit interfaces and error handling within functions. Tooling includes versioning, build, and formatting tools as well as IDE support. Concurrency is easy with goroutines and channels, and debugging can be done with print statements or GDB.

5. Simple language to learn
Golang. there is only
one way
Opposite of Perl in certain sense. Strict pre
defined implicit type declaration
@i = ( 1, 2, 3 );
becomes
i := []int{1, 2, 3}

6. Lets print something
❖ Print text
❖ print “Hello World”;
❖ fmt.Printf(“Hello Worldn”)
❖ Print text to file
❖ print $fh “Hello World”;
❖ fh.Write(“Hello Worldn”)

7. For sake of simplicity
❖ Golang does not have
❖ Implicit conversion between
types
❖ Classes
❖ Implements
❖ Pointer Arithmetic
❖ Exceptions
❖ Generics

8. For sake of simplicity …
❖ Golang has
❖ Implicit interfaces
❖ Error handling within realm
of function
❖ Error returns

9. Tooling
❖ Versioning
❖ Build
❖ Formatting available as CLI
tools
❖ Supports several IDEs

10. There is concurrency
❖ Concurrent code is easy to
write
❖ Either with semaphores
❖ or Go routines and channels
❖ Simple
❖ Can be parallelized in presence
of more than 1 CPU

11. Debugging
❖ log.Printf(“%v”, obj)
❖ GDB is also capable of stepping through go binary
