Question: What is Range?Answer:Range is a great way to declare continuous variables. You should use it to declare arrays and other types of collections. range1 = (1..4).to_a => [1, 2, 3, 4] puts range1 1 2 3 4 You can also create strings in this format and it fills in the interim values automatically. range2 = ('bar'..'bat').to_a puts range2 bar bas bat Since the end result of using range is an array you can also iterate over it just like any other array. range2.each do |str| puts "In Loop #{str}" end This produces the result as shown below: In Loop bar In Loop bas In Loop bat |
