Keeping your code organized and optimized is one of the most challenging tasks for all developers. Irrespective of whichever platform you are working on, precise and clean coding will help you better understand the intent behind the code by making source files sophisticated and understandable for everyone who reads it. 

Here are the tools that make your job easy of keeping your Rails Code Clean.


In your code, there would be a specific group of snippets that happen to be present and does not enhance any feature or add any value to your project. These lines of codes use your resource and might

make your application slower, so they have to be removed for better functioning of your product.

As a developer, you might want to check the processing speed of the code. If you wish, you can then decide to optimize the system if the speed is not up to the mark. Database connectivity, image loading speed, DOM loading, etc. are the areas you should focus on.
