JavaScript vs Ruby: Everything you need to know

JavaScript and Ruby are not the same. JavaScript is an object-oriented front-end scripting language with the help of the node.js framework. It can be utilized in the back-end process to replace PHP. In contrast, Ruby is an object-oriented, general programming language, with ruby on rails (framework); it functions in the back-end same as PHP.

The gap here is because of the frameworks: ruby on rails and node.js. Without them, they both are poles apart from each other.

For a beginner, it is hard to catch the point. A language has no certain limits, so we can not accurately throw a certain opinion on its workarounds.

So the question is what frameworks are, so they are like plugins to extend languages’ functionality. For instance, JavaScript or typescript naturally is only for a client-side scripting language. Yet, with the help of the Node.js framework, developers manage this to be used on the server-side.

In the Same way, ruby is a general programming language, similar to python and R, yet a big part of this programming language is involved in web development. Reasoning the framework “Ruby on rails,” which makes this language useful, works similar to JavaScript with node.js.

Ultimately this draws a big complexity to get the idea of both of these languages, so starting with the below some major contrasts.

JavaScript vs Ruby: Differences

ParameterJavascriptRuby
PurposeIt is developed for web pages. It can change a static web page to turn into a dynamic web page.It is developed for beginners to code with ease. Mainly web development made easier.
Easy to learnIt is difficult to understand JavaScript syntax for a newbie.It is easy to get started with, and syntax are as simple as python.
PerformanceIt is said about javascript. It is almost 4times faster than Ruby in a few operations.When comparing its performance against javascript, ruby is slower.
OOPS It is an object-oriented scripting dynamic language. Interpreted rather than compiling when running.It is also an object-oriented, dynamic interrupted language.
Full-stack developerJavaScript can be used as the full-stack web development; node.js helps in back-end handling.Ruby is not considered as the full-stack web development language. Only good for handling the back-end process of a large-scale app.

The table is showing some similarities as well. A few of them are: Both are interpreted, OOP, language, if you notice the main similarity: they can be used for handling a back-end process. That’s where things get screwy.

If you’re facing hard times to understand what these terms are like, OOP, compiled, interpreted.

Here is a brief introduction to them.

What is OOP?

Object-oriented programming (OOP) is a sort of writing computer programs using “objects” to stand for data and methods. This way, it becomes easy to call a function from the object rather than creating repeatedly.

What is a compiled language?

Programming is like ordering a machine to do a certain task; Compiler languages are those who naturally understand the code you write and forward it to the machine. Once for all. Hence, they are fast. Few examples; C, C++, GO.

What is an interpreted language?

Interpreted languages are those who do not already understand the commands unless you write them. When you write a specific code and interrupted language, it first understands itself later and sends that specific command to the machine. They are technically slow.

Few examples are; Ruby, Javascript, PHP.

What is javaScript?

The fundamental definition of this language says: it is a scripting or programming language that grant us to implement complex elements on web pages, used for displaying timely content updates, maps, 2D/3D animation, scrolling videos, pop-ups, and any dynamic behavior you see on a webpage is due to this language.

That’s said, almost 90% of webpages contain JavaScript codes on their front-end.

But without HTML and CSS JavaScript hardly could do anything. The developers say that it is the third layer of a cake.

Meaning that it needs a static structure to change it into dynamic. And you might already be familiar with the HTML language, the only language useful for creating structure. And CSS for filling color-gradients, and styling.

Regardless of saying it is only a language for the client-side, many companies nowadays use JavaScript to manage the back-end process using the framework node.js.

What is Ruby?

Ruby is a general programming language. Like python, it has a wide range of working applications like data analysis, prototyping, logic, and web scraping. In short, the list has no fixed endpoint.

The Ruby language is probably the easiest language. That’s said, a beginner with no background knowledge of programming could quickly get the idea of the codes written in Ruby.

Despite the fact it is a general language, it is mostly used in web development when mixed with Ruby on rails framework, which turns this into the server-side scripting language, which means you don’t need to use either node.js and PHP.

If you wondered what PHP functions? It retrieves data from the database and displays it to the users depending on the query.

However, PHP’s syntaxes are difficult; therefore, the ruby on rails has gained so much popularity over the past years, the number of its users is increasing day by day.

Lastly, already there are many popular websites built up by using Ruby. Including Airbnb and the TV streaming service Hulu. Other applications include Github, Goodreads, and the calorie-tracking application, so forth.

What is Ruby on rails?

Ruby on Rails is a tool/ framework developed in ruby language. It was first released in 2011 for the reason that everyone can adopt web development in the simplest way possible.

That’s why it has gained so much love, mainly from the beginners.

It is easy to learn and has the simplest syntax, but at the same time, it is a powerful language that lets you develop a big application in a matter of minutes.

The main advantage of ruby on rails over JavaScript with node.js is the ease it provides. With this, you will get everything set up already. For instance, let’s say you want to link a login forum to your database, so if you use JavaScript with node.js, you will have to build everything from the start.

With this same task, ruby on rails can easily do; it has already formatted such snippets that a developer needs to arrange with minimal effort. Based on that, ruby rails is the far better choice for many people.

At this stage, you should have enough understanding regarding them. In order to figure out more of the details, this below comparison might benefit you.

Features comparison- Ruby vs. javaScript

Nature

Both languages are the same by nature yet have some contrasts in the working areas.

  • JavaScript is an object-oriented, dynamic scripting language and has interrupted ability.
  • Ruby is also an object-oriented language by nature, but it is a general-purpose language. And its codes work on the principle of interruption.

Frontend or backend?

In spite of the fact that JavaScript can be used in the front-end as well in the backend, ruby can only be used in the back-end. You must have to learn the ruby on rails framework for this either. These two have back-end handling abilities that make them similar up to some extent.

  • JavaScript can be used as a front-end and back-end language using the same language.
  • Ruby in web development is only used in the back-end using ruby on rails.

Speed performance

Both languages have a great place at their places. Generally, JavaScript is faster than Ruby. It’s also said that the apps built by using JavaScript are lighter than Ruby. Node.js is not suitable for handling large data. But when it comes to something big, mainly server-side, then ruby on rails is the way to go.

  • JavaScript is faster than Ruby in some cases.

Popular

It’s said about JavaScript all over the internet. The greatest part of the websites is using JavaScript codes, whereas Ruby, with its robust framework, is also leaping forward in web development.

  • Some big companies that use javascript

These companies use JavaScript as the full-stack web development.

  1.  Instagram
  2. eBay
  3.  Codecademy
  4. Firebase
  5. Groove shark
  6. Square
  7. sentry etc
  • Some big companies that use Ruby.

These companies use Ruby’s popular framework, “Ruby on rails.”

  1. Rap Genius,
  2.  Instacart,
  3. Task Rabbit,
  4. Fab,
  5. Scribd

Developers pay

The expert developers in both these languages are paid well by the companies; in 2021, the job opportunities of both are quite high.

Community

Both languages have a wide community. However, JavaScript with node.js users is limited, whereas ruby with ruby on rails has a wider community.

  • JavaScript has a narrow community compared to a ruby.
  • Ruby after the ruby on rails in 2011, the community has grown dramatically and keeps moving with the same velocity.

Which one do you use?

Generally speaking, JavaScript is the best choice for people who have more interest in web development. With javascript, you can be a full stack developer. Using it, you can set up the front-end and also manage the backend.

Ruby is for general purpose. It is better to put this language head to head with a similar language like python.

Meaning that if you learn Ruby, you can build some programs for sure, but it’s not actually beat JavaScript in web development.

Ruby indeed has the framework “ruby on rails” which makes it easy to handle server-side tasks; however, it does not have any feature to beat JavaScript when implemented in the front-end.

You cannot be a full-stack web developer with ruby and ruby on rails. However, you may get an excellent job as a web developer.
