Ruby | Range new() function

Ruby is a popular programming language that offers a lot of powerful tools and features for developers. One of these features is the Range new() function, which is used to create a new range object in Ruby.

What is a Range?

A range in Ruby is a sequence of elements that are defined by a beginning and an end. For example, the following code creates a range from 1 to 10:

range = 1..10

This range includes all the integers between 1 and 10, including 1 and 10 themselves.

The Range new() function

The Range new() function is used to create a new range object in Ruby. It takes two arguments: the beginning of the range and the end of the range.

Here's an example of how to use the Range new() function:

range = Range.new(1, 10)

This code creates a new range object that includes all the integers between 1 and 10, just like the example above.

The Range new() function can also take a third "exclude end" argument, which can be set to true or false. If this argument is set to true, the end of the range will be excluded. Here's an example:

range = Range.new(1, 10, true)

This code creates a new range object that includes all the integers between 1 and 9, but excludes 10.

Conclusion

The Range new() function is a powerful tool in the Ruby programming language. It allows you to create range objects with ease, and gives you control over whether the end of the range is included or excluded. If you're working with ranges in Ruby, the Range new() function is definitely worth checking out.
