Description
The rule “Prefer proc over Proc.new” is an important guideline in Ruby programming. It advises developers to use the proc method rather than Proc.new when creating a new Proc object. The proc method is more idiomatic to Ruby and is preferred because of its simplicity and readability.
The importance of this rule lies in maintaining consistency and clarity in your code. Using proc instead of Proc.new makes your code more concise and easier to read and understand. It also aligns with the Ruby community’s best practices, which favor simplicity and readability.
To avoid violating this rule, always use proc when you need to create a new Proc object. For example, instead of writing Proc.new { |n| puts n }, you should write proc { |n| puts n }. This small change can significantly improve the readability of your code.
