Ruby | range.end() function

Introduction

Ruby is a dynamic, interpreted programming language known for its simplicity, flexibility, and readability. Ruby has a rich ecosystem of libraries and frameworks that make it a popular choice for web development, game development, machine learning, and more.

In this article, we will explore the range.end() function in Ruby.

The range.end() Function

A range is an object in Ruby that represents an interval of values. A range is created using two or three dots (.. or ...) to define the endpoints of the range. For example:

range = 1..10 # includes 10 
range_exclusive = 1...10 # excludes 10 

Once we have created a range, we can use the range.end() function to retrieve the end point value of the range.

range = 1..10 
end_point = range.end() # 10 

For an exclusive range, the range.end() function returns the endpoint value - 1.

range_exclusive = 1...10 
end_point_exclusive = range_exclusive.end() # 9 

Conclusion

The range.end() function is a useful method in Ruby for accessing the endpoint values of a range. Understanding how to work with Ruby ranges is an essential skill for any Ruby programmer.
