How do you print a text string in Ruby?
puts is a Ruby method that tells the computer to print some text to the screen. The puts method is then followed by a sequence of characters — Hello, World!, enclosed in quotation marks. Any characters that are inside of quotation marks are called a string. The puts method will print this string to the screen when the program runs.
How does the Ruby interpreter execute the line puts?
The Ruby interpreter read the file you specified and evaluated its contents. It executed the line puts “Hello, World!” by calling the puts function. The string value of Hello, World! was passed to the function. In this example, the string Hello, World! is also called an argument since it is a value that is passed to a method.
