As said earlier in a previous blog, the Ruby on Rails framework is a mature programming language that has evolved over the years. With a large community across the globe, you can expect great support and new features every time. One must note that the RoR programming language is open-source and cost-effective, but has some technical glitches and performance limitations.

However, Ruby on Rails developers are always making it more productive and efficient by infusing new features. Compared to the Ruby 2, 2013 version, the latest Ruby 3.0 harnesses three new features for building top-notch web applications.

Ruby 3.0 latest features

The number 3 is significant in the latest Ruby programming language release. The Ruby 3.0 is primarily for

  1. Being faster 
  2. Having better concurrency
  3. Ensuring correctness
  4. Why you should choose Ruby programming language for web app development 

Let’s have a look at the 3 latest features of the RoR programming language 3.0:

1. Improved performance

Poor performance was one of the challenges with the earlier Ruby on Rails platform. Matz, Tender Love, and Koichi are the three major contributors that have aimed to make the platform better and more efficient.

If fastness was the only goal, RoR would be much different than it is today, he added. Instead, developers have focused on two performance areas that can be measured and optimized: memory and CPU.

a. CPU optimization:

Some enhancements in Ruby internals have been made to improve speed. The Ruby team has optimized the JIT (Just In Time) compiler as compared to the earlier version. The modern MJIT compiler comes with better security and speed features to ensure optimal web app performance.

MJIT (method-based JIT) implementation is quite different from the usual JIT. When methods get called repeatedly, MJIT will pick methods that can be compiled into native code and put them in a queue. Later, MJIT will fetch the queue and convert it to native code

b. Memory optimization:

It is always imperative to clear the garbage while processing a code. Ruby 3 comes with an advanced garbage collector similar to Python’s buffer-like API, which helps with better memory optimization.

Since Ruby 1.8, Ruby has continuously evolved Garbage collection algorithms, including the introduction of a manual Garbage Compaction method in version 2.7. The modern Ruby 3.0’s Garbage Compaction is fully automatic and optimizes the memory to a great extent.

c. Objects grouping:

The garbage compactor moves objects in the heap. It groups dispersed objects together at a single place in the memory so that this memory can be used by heavier objects later.

2. Parallelism and concurrency

Concurrency is one of the important aspects of any programming language. Matz feels that the threads are not the right level of abstraction for Ruby programmers to use.

There are several features and improvements made in Ruby 3.0 to make applications efficient where concurrency is a major focus.

a. Fibers:

Fibers are considered a disruptive addition in Ruby 3. Fibers are lightweight workers similar to Threads with some advantages. Unlike Threads, Fibers consume less memory and give greater control to the programmer to define code segments that can be paused or resumed, resulting in better I/O handling.

b. Fiber scheduler:

Fiber Scheduler is an experimental feature added in Ruby 3. It was introduced to intercept blocking operations such as I/O. The best thing is that it allows lightweight concurrency and can be integrated into the existing codebase without changing the original logic.

c. Ractors (Guilds):

Ractor is an Actor-Model concurrent abstraction designed to provide a parallel execution without thread-safety concerns.

Ractors allow Threads in different Ractors to compute at the same time. Each Ractor has at least one thread, which may contain multiple fibers. In a Ractor, only a single thread is allowed to execute at a time. Thus improving the overall RoR programming language performance.

3. Static analysis

Tests are needed to ensure the correctness of the RoR programming language. Though it comes with built-in testing tools, the Ruby 3 version was enhanced to make the code more reliable. Static analysis can also be a great tool to ensure the correctness of a Ruby program.

The static analysis relies on inline type annotations which aren’t DRY. The solution to address this challenge is having “.rbs files” parallel to our “.rb” files.

a. RBS

RBS is a language to describe the structure of a Ruby on Rails program. It provides us with an overview of the program and how overall classes and methods are defined.

Using RBS, we can define the Ruby classes, modules, methods, instance variables, variable types, and inheritance. It supports commonly used patterns in RoR code and advanced types like unions and duck typing.

Why is the Ruby on Rails framework an ideal programming language for web application development?

We’ve already explained the unique features of the RoR programming language in our earlier blog. Now, let us walk you through what has made the Ruby framework a leader in web app development for years.

  1. A suitable solution for MVP development. 
  2. RoR is all about quality.
  3. You can build simple yet successful mobile apps.
  4. Web applications built on Ruby are secured and well-tested. 
  5. You will get unmatched community support across the globe. 

Myths of Ruby on Rails programming language

Ruby on Rails is an amazing framework that can be used to build profitable web and mobile apps. Despite its popularity, numerous myths have shrouded the RoR platform for years. As a leading Ruby on Rails development company, we say the following are far from the truth.

  1. Rails programming is dying 
  2. RoR platform is slow
  3. Ruby on Rails programming is costly
  4. RoR programming language is not scalabl

Let us debunk the top myths of the RoR programming language.

Myth 1: The RoR programming language is dying/losing its charm

There will always be a big hype and misconceptions around new technology. It is the same with the Ruby programming platform, which is reaching a saturation or mature level, resulting in gossip about its performance and scalability.

But, the rumors about the Ruby framework are not true. Recently, we compared the Ruby 3.0 version, a powerful and automated version, to earlier versions. Additionally, Ruby has an active developer community that is always contributing to the platform’s improvement.

Myth 2: Ruby on Rails programming platform is slow

If you recall our above statement, Ruby on Rails programming was not designed for speed, but to enhance the developer’s experience and productivity. That said, this myth about RoR being slow was not really a myth—it was true. However, with the recent update of Ruby 3.0, improvements have been made to optimize memory and CPU performance.

Unlike other web programming platforms, Ruby on Rails comes with built-in tasks such as file structures, database, configure files, and established communication between the codes—making the platform reliable and faster.

On the other hand, the Ruby programming language is fully automated. It comes with in-built testing features, making the code error-free and saving time.

Myth 3: Ruby on Rails app development is costly

You might search “what is the cost of web application development using Ruby on Rails?“. And, the results might lead you to a misconception about the Ruby on Rails development framework that it is costly and that SMEs can’t afford it.

Let us put this myth to rest for you.

First, RoR is an open-source framework that is available for free.

Second, the immense community support of RoR has made it a reliable web application development framework.

But why do most people think the RoR platform is costly?

Despite the technology, there is always discussion around good and bad development experiences. If you have had plans to adopt the RoR programming language for your web app and fail to hire or collaborate with an experienced team of RoR developers, it would cost you more than estimated.

Therefore collaborating with an experienced tech IT staffing company or an offshore dedicated teams services provider could get you a perfect RoR-based solution within your budget.

Myth 4: Ruby on Rails has scalability issues

One of the biggest myths about the RoR programming language is that it has scalability issues. With Ruby on Rails, you can build an application with isolated services. But you should know how to use this platform correctly and how to optimize the code to ensure better productivity and efficiency.

Before making the code scalable, it is essential to identify the factors responsible for slowing it down. If the Ruby on Rails developer has a deep understanding of the platform, they can make the code independently handle services such as security, load balance, and scalability.

There are available solutions to address the scalability challenge of the RoR platform:

  1. Code optimization 
  2. Horizontal scalability
  3. Service-oriented architecture
