Ruby is an advanced solution that allows web developers to fill in various functionalities in the application using the `Gems`.
Do you know about Ruby Gems and their usability?
Usually, a web app development takes months, but using the ‘Gems’ it can be built in a few days. They are modular and offer the advantage of high performance. Moreover, their integration into the new applications is very easy. Ruby community has created a huge number of gems for the use.
