Data can be expressed in the form of a range using Ruby Ranges (in other words a data set with start and end values and a logical sequence of values in between). Numbers, characters, strings, and objects can all be used as range values.

This is a simple and general approach to define ranges in Ruby so that consecutive values in the sequence can be produced. It has a beginning and a conclusion. Ranges are created using two operators: the Double Dot (..) operator and the Triple Dot (...) operator.

The range operators ".." and "..." are used by Ruby to produce these sequences. The two-dot form creates a range that includes the provided high number, but the three-dot form creates a range that excludes it.

The range() function returns a number series that starts at 0 and increments by 1 (by default) before stopping at a specified value.

The range operator is a type of operator that defines a sequence of values. The range operator is denoted with two dots (e.g. ..). It can be used in various programming languages to define a sequence of values that can be iterated over and used in different operations.
