How to Use Multiple Conditions

You can do this by using the && (AND) operator:

if name == "David" && country == "India"
      #statement 1 -----------
      #statement 2 -----------
end

You can also use the || (OR) operator:

if age == 10 || age == 20
      #statement 1 -----------
      #statement 2 -----------
end
