Advantages Of Javascript

JavaScript is commonly used in web development for several reasons:

  • Versatility: JavaScript is functional on both the client and server ends of websites. This makes it possible to create whole web apps with just one language.
  • Interactivity: It lets you make dynamic and interactive user interfaces. For example: doing form checks and showing real-time updates without reloading the page.
  • Big Ecosystem: There are many libraries and tools for JS, such as React and Angular. These make web development easier and faster.
  • Works Everywhere: All major web browsers support JS. As a result, code runs the same no matter what browser or system someone’s using.
  • Asynchronous Programming: JS can handle many tasks at once without getting stuck. This makes web apps faster and more responsive.

Disadvantages Of Javascript

JavaScript (JS) is heavily utilized in the field of web development. However, there are a few issues with it:

  • Compatibility Issues: Issues of compatibility may arise when incorporating JavaScript into established enterprise systems. Hence, you may need extra effort.
  • Concerns about maturity: The different levels of maturity in JavaScript frameworks and libraries can result in reliability and stability issues.
  • Security threats: JavaScript applications depend greatly on third-party modules. This raises the risk of security flaws. This is more accurate if the app is not effectively controlled.
  • Scalability challenges: Scaling applications across multiple CPU cores can be a difficult task. This is especially true for high-traffic or large-scale projects.

Difference Between Ruby On Rails Vs Javascript

Here’s a simplified comparison table between Ruby on Rails and JavaScript. This table gives a basic summary. Choosing between Ruby on Rails and JavaScript depends on many factors to consider.

Aspect Ruby on Rails JavaScript
Coding Speed & Development Time Faster due to conventions and vast libraries Slower due to framework selection, but more flexible for unique applications
Performance Sufficient for most applications, but not ideal for highly intensive tasks Faster and more scalable with modern frameworks
Server-side vs Client-side Server-side framework Primarily client-side scripting language, but frameworks like Node.js enable server-side functionality
Development Cost Potentially lower due to faster development and wider developer pool Can vary depending on framework and complexity, may require hiring specialists
Security Offers baseline security features Security depends on framework and development practices
Scalability Requires adding more server resources, may be complex for massive user bases Modern frameworks offer horizontal scaling for easier handling of increased load

Here’s a more detailed breakdown comparing Ruby on Rails and JavaScript. It is based on the specified factors:

Difference Between Ruby On Rails Vs Javascript

Coding Speed & Development Time

Ruby on Rails: With its popularity of “convention over configuration” tactic, Rails offers ready-to-use templates and features. It cuts off the developers from writing much of the code, thus enabling them to work swiftly. What is more, rail community users also have a vast library of reusable code modules that help to simplify development.

JavaScript: While JS in itself can be written fast, most applications need to make use of some specific frameworks and libraries. Picking the well-fit ones take some time initially, but the smoothness provided by JavaScript can be of good use in the development of highly specific applications.

Verdict: Ruby on Rails excels in rapidly developing standard features, while JavaScript is more flexible for unique applications, despite longer development time.


Ruby on Rails: Rails is a full-featured framework incorporating both server-side coding and data processing operations. This might not be so fast for highly intensive applications and, therefore, less performant in some JavaScript frameworks, which are optimized for speed.

JavaScript: Modern JavaScript frameworks such as Node.js employ performance and scalability to achieve higher load capacity. In addition to managing data flow in real time and dealing with intricate user handling, they are best for those applications that are targeted to be as responsive as possible.

Verdict: JavaScript frameworks are ideal for speed and real-time functionality, while Rails provides faster development and sufficient performance for most business applications.

Server-side vs Client-side

Ruby on Rails: Rails is a server-side framework, unlike some other frameworks, which are client-side. This translates to the code running on the web server carrying out activities such as database connections, user authentication, business logic, and many more. The processor is then used to process it and send the processed data and instructions to the user’s browser for display.

JavaScript: JavaScript is primarily a client-side scripting language. It runs directly in the user’s web browser, manipulating the user interface and handling dynamic interactions like form validation or animations. However, JavaScript frameworks like Node.js have extended its reach to the server-side as well.

Verdict:  Rails is work behind the scenes, while JavaScript is the actors on stage.

Development Cost 

Ruby on Rails: The fast development provided by Rails is often a big reason for the decrease in development cost over time. Additionally, Ruby on Rails programmers are quite handy, and compared with certain niche JavaScript frameworks, the hiring cost can be lower.

JavaScript: The cost of JavaScript development can range reasonably, depending on the selected framework and the application’s complexity. Although there’s a large base of JavaScript developers, searching for field specialists could be more costly.

Verdict:  For budget-conscious projects with standard functionalities, Ruby on Rails can be a cost-effective choice


Ruby on Rails: In rails, security features have been added that defend against SQL injections and cross-site scripting that are common among web application vulnerabilities. While, on the one hand, constant monitoring and security updates are the key component of any framework.

JavaScript: The security of JavaScript applications depends virtually on the framework and development techniques used. JavaScript requires proper coding practices and security audits periodically to reduce risks.

Verdict: Rails offers a baseline level of security due to its built-in features.


Ruby on Rails: Scaling a Rails application typically involves adding more server resources like CPU and memory. This can be sufficient for many businesses, but for highly scalable applications with massive user bases, it might require more complex infrastructure management.

JavaScript: Modern JavaScript frameworks like Node.js are known for their horizontal scaling capabilities. This means you can distribute the application logic across multiple servers, making it easier to handle increasing user loads.

Verdict: For applications expecting significant growth, JavaScript frameworks provide built-in scalability options, while Rails can be scaled effectively.
