Javascript vs Ruby: The Key Differences That You Should Know

Are you interested in knowing about some essential differences between Javascript vs Ruby? If yes, then you came to the right place. We know that Javascript vs Ruby is always a big concern among the students. Before going deeper, Let’s start with a short introduction to each of these terms.

What is JavaScript?

JavaScript is a dynamic programming language for computers. It is lightweight and is most commonly used as a component of web pages, where implementations enable client-side script to interact with the user and create dynamic pages. It is an object-oriented programming language that can be interpreted.

JavaScript was originally known as LiveScript, but Netscape changed its name to JavaScript, possibly due to the buzz generated by Java. JavaScript first appeared in Netscape 2.0 in 1995 under the name LiveScript. The language’s general-purpose core is embedded in Netscape, Internet Explorer, and other web browsers.

What is Ruby?

Ruby is a scripting language and it was designed by using Linux mostly. It is compatible across all platforms, including UNIX, Windows, DOS as well as Mac OS, etc. Its straightforward syntax makes it simple to write and read in the event that we are already familiar to other languages of programming, such as Python.

Ruby was developed by Yukihiro Matsumoto, and was first launched in 1995. Ruby is very similar to Smalltalk and Perl since it’s objects-oriented, similar to Smalltalk and is as simple to use as Perl which makes it simpler to maintain.

Javascript vs Ruby: The Key Differences

There are so many differences in between the Javascript vs Ruby and some of them that are the important ones are shown below:

  • JavaScript as well as Ruby are dynamic, object-oriented and general-purpose scripting languages which interprets and not compiled at the runtime.
  • JavaScript can be used as a the front-end as well as back-end language, with the same language while Ruby can be utilized as an back-end programming language.
  • JavaScript is more scalable than Ruby since it’s 20 times quicker than Ruby in some instances.
  • A lot of companies utilize JavaScript and some of them include eBay, Codecademy, Groove shark, sentry, Firebase, Instagram, Square, etc. Many companies also use Ruby Some of them include Intuit, Instacart, Scribd, Task Rabbit, Rap Genius, Fab, etc.
  • Ruby applications can be difficult to debug because they have several layers of abstraction, because of which it can take longer to correct bugs, while JavaScript applications are simple to fix in comparison to Ruby.
  • JavaScript can be integrated into various applications, including Yarn, Buttercup, Auth0, cell, Parcel, and Apache Open whisk etc. While Ruby is compatible with a variety of applications, including Auth0, Rails, Pow, Sinatra, Lita, Bitrise, Carrier Wave etc.
  • JavaScript does not have the ability to track memory usage however Ruby is able to do so.
  • Ruby is a better choice for applications that require a lot of CPU application development that involves images, graphics processing, and so on. However, Node.JS isn’t suited to that require a lot of CPU application development.
  • Ruby has support from the online community which is involved among all open source frameworks however JavaScript has documentation as well, but for some npm modules their is a lack of documentation.
  • JavaScript applications are simple to create, however, for Ruby development, programmers those are experienced ones are needed with high pay.
  • JavaScript can be used to perform Full stack development due to its node.JS framework, while Ruby isn’t able to be used as full Stack.
  • JavaScript has some drawbacks such as it’s inefficient for CPU-intensive tasks, inconsistency, not be able monitor memory utilization and so on. Ruby has drawbacks like performance, memory hogging and the ability to read code.

JavaScript vs Ruby: In Tabular Form

The table below is a comparison table of JavaScript vs Ruby

The basis of comparisonJavaScriptRuby
OOPSJavaScript is an object-oriented, dynamic programming language that interpret instead of compiling during the runtime. We can make elements known as object and manipulate the data of objects by programmers.Ruby is an object-oriented flexible general scripting language that interprets instead of compiling at runtime, which allows object creation. Additionally, a users can alter multiple files at the same time with the help of objects created by programmers.
Programming LanguageJavaScript is a front-end programming language that is typically used to facilitate client-side application, server-side, interactions and modifications at the browser level.Ruby is a back-end programming language through which we can create JavaScript as well as HTML pages which run on the server-side and interact with databases.
Syntactic DifferenceIn JavaScript the declaration of variables and assignment are a little more extensive than Ruby in the following manner

var var_name= value

and Hashes are considered to be objects. You can access the value using 

In Ruby the declaration of variables and assignment is easy to compare to JavaScript according to:


and Hashes are described as

hash_name={key:value,key1:value1} and access key’s value as

PerformanceJavaScript is 20 times more efficient than Ruby in certain instances due to its engine that is highly optimized.Ruby’s performance is extremely slow, making it a bottleneck. Due to the abstract nature of Ruby applications, debugging them can be a time-consuming and difficult process.
When to UseJavaScript is a good choice when your application requires to be developed in a shorter amount of time, perform better and scale.Ruby can be utilized when we create applications that use a large amount of CPU heavy applications, rapid application development with just a few lines.
ScalabilityJavaScript is more adaptable than Ruby because of Node.JS since it gives greater performance and fewer of servers.Ruby isn’t as flexible as JavaScript is, so many businesses have switched away from Ruby to JavaScript because of its scalability like such as the New York Times, LinkedIn, Uber, PayPal etc.
Learning CurveJavaScript includes a wealth of documentation as well as online sources, forums, and online communities that allow users to learn quickly as we watch its immediate implementation within the browser. If we wish to build websites or web-based applications, it is possible to learn JavaScript.Ruby offers a variety of ways to learn from online sources, forums online and communities that allow us to learn by ourselves. The majority of Ruby is utilized by the top websites, applications.
