5. Clean code is the code that is easy to read, understand, and maintain What is clean code?
6. Readability and maintenance: Clean code prioritizes clarity, which makes reading, understanding, and modifying code easier. Writing readable code reduces the time required to grasp the code's functionality, leading to faster development times. Why clean code is necessary?
7. Team collaboration: Clear and consistent code facilitates communication and cooperation among team members. By adhering to established coding standards and writing readable code, developers easily understand each other's work and collaborate more effectively. Why clean code is necessary?
8. Debugging and issue resolution: Clean code is designed with clarity and simplicity, making it easier to locate and understand specific sections of the codebase. Clear structure, meaningful variable names, and well-defined functions make it easier to identify and resolve issues. Why clean code is necessary?
9. Improved quality and reliability: Clean code prioritizes following established coding standards and writing well-structured code. This reduces the risk of introducing errors, leading to higher-quality and more reliable software down the line. Why clean code is necessary?

11. Coding convention Go Back to Agenda Page
12. Coding convention Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language.
13. Coding convention These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventions, programming practices, programming principles, programming rules of thumb, architectural best practices, etc. These are guidelines for software structural quality.
14. Coding convention Different organizations have different coding conventions and code styles

17. How can we implement coding rules in Ruby?
18. Rubocop and setup Go Back to Agenda Page
19. Rubocop RuboCop is a Ruby code style checker (linter) and formatter based on the community-driven Ruby Style Guide. RuboCop is extremely flexible and most aspects of its behavior can be tweaked via various configuration options. In practice RuboCop supports pretty much every (reasonably popular) coding style that you can think of. Apart from reporting problems in your code, RuboCop can also automatically fix some of the problems for you.

23. https://github.com/prontolabs/pronto Pronto runs analysis quickly by checking only the relevant changes. Created to be used on GitHub pull requests, but also works locally and integrates with GitLab and Bitbucket. Written in Ruby Pronto
