Choosing the right framework is one of the most important decisions when taking on a software development project. It can influence everything from project execution to long-term maintainability. In this comprehensive comparison, we dive deep into two widely used technologies: Ruby on Rails vs JavaScript.

What is Ruby on Rails?

Ruby on Rails, often shortened to Rails, is a server-side web application framework written in Ruby, a dynamic, object-oriented programming language. It’s licensed under the MIT License, ensuring wide accessibility and adaptability for developers.

Rails employs a model–view–controller (MVC) framework, a widely adopted architectural pattern in professional web development. This structure offers default setups for a database, a web service, and web pages, streamlining the development process significantly​​.

JavaScript, often at the heart of web development, is a programming language that’s become indispensable in building dynamic, interactive websites. It allows developers to create content that updates dynamically, controls multimedia, and animates images

The possibilities are nearly limitless with JavaScript – from making web pages respond to user actions to powering complex web applications​​.

Advantages of JavaScript

According to a 2023 HackerRank report, JavaScript ranks as the fifth most popular language companies seek in a web developer in 2023. And the rise of TypeScript (built on JavaScript) has further strengthened the language’s popularity.​
