Line 24:

The language was created by [[Yukihiro Matsumoto]] on February 24, 1993. The

current stable version is 1.6.6 (26-12-2001)7. Note that the name is not an

[[acronym]]--it is actually a [[pun]] on [[Perl]]. According to the author, he

designed Ruby to follow the ''principle of least surprise'' (POTS), meaning that the

language should be free from the traps and inconsistencies that plague other

languages.

<pre>

# Execute the following block of code 10 times

string1 = "Hello world" # assign "Hello world" string to variable 'string1'

10.times {

string2 = string1.gsub(" ", ", ") # replace all " " by ", " in 'string1', put result into variable 'string2'

string1 = "Hello world".gsub(" ", ",") # Replace ' ' with ', ' and store in string1

string2 += "!\n" # append "!\n" ("\n" is newline character) to variable 'string2'

print string2 string1 += "!" # printappend "!" to variable 'string2string1'

puts string1 # print variable 'string1', followed by a newline

}
