import "fmt"
func main() {
fmt.Println("Hello, World!")
}
20. "Hello World" Program in Julia
Julia is a high-performance, high-level, open-source, dynamically-typed programming language. Julia was created by combining the powerful features of other programming languages like C, Ruby, Lisp, Matlab, Python, R, and Perl.
println("Hello, World!")

You've forgotten the "#" on the title of the number 6 ;)
And on the number 19 it should be "Go" in the title :)
I fixed that , thank you for your feedback :)
Transcript show: "Hello world!".
Frankly we have to come up with a better intro program than "Hello World".
Long gone are the days when printing something on the terminal meant something or was exciting.
Today's basic program should be something like draw a square on the screen. Then we shift the focus towards terminal programing to something more real for this era like the browser, a window, a mobile app, or a something else. Even on the terminal it's possible.
Here's a box in logo:
repeat 4 [ fd 100 rt 90 ]
Why #15, #16 both Perl??
I fixed that , thank you for your feedback :)
Typo number 12 word Ruby
In stead of printing "Hello World", I write like the following :
package main
import "fmt"
func main() {
fmt.Println("I am learning Go aka Golang")
}
That is what I do with other programming language like Dart with Flutter or React Native.
I wish you would include "Hello World" in Assembly language, esp for Intel 8086 family or Motorola. :)
I think for Ruby in #12 should be:
print "Hello, World!"
:)
The 1st programming language that gave me money would output the same result with the following :
@2, 10 say "Hello World"
:)
Sadly, now that language is extinct, like the then loved language which would produce the same result with :
Begin
writeLn("Hello World");
End
