Ruby 3 Released Features with Enhanced Performance

Ruby is a scripting language developed for use in front-end and back-end web development. It is a language of careful balance and is a robust, dynamically typed, and object-oriented language.

It has an easy-to-understand high-level syntax. Ruby is an interpreted language rather than a compiled one and is designed to be both fun and at the same time productive as well.

It has been seven years since 2013 that we are all been using Ruby 2, many improvements to the language have helped large many people and projects.

Finally, the wait is over, Ruby 3.0 has been released this Christmas and is approved by Matz, which has been the creator of Ruby in his last presentation.

Ruby 3 is an exciting update packed with lots of features that make it appealing for now and in the future with multiple point updates ensuring even more features.

Ruby3 has overcome its shortcomings and deficiencies existing in the previous version, it has become faster. Its new upcoming features will surely lift the bars and the new version of Ruby appears to be specifically designed to make it faster, correct, and concurrent.


How is Ruby 3.0 is Different?

Ruby 3’s main marketing feature is that it is 3 times faster than Ruby 2. This new version has a lot to bring with tons of features within the latest version of Ruby. It has also been ensured that performance is improved and that backward compatibility is still maintained.

Its third version includes a whole bunch of new additions like type checking, scheduler, and ractor, along with other changes to the currently existing paradigms, like performance, memory, fibers, concurrency, and static analysis.

Features and Major Areas of Improvement of Ruby 3:


1) Performance

Ruby 3 is supposedly 3 times faster than Ruby 2. However, the previous version has not shown this particular update in its full strength, we are still hoping that this final version will live up to the expectations.


2) Parallel Computing

Ruby 3 now supports parallel computing with the help of Ractors.

3) Type Checking

Ruby 3 includes RBS, a gem that provides parsing and processing type definitions written into it. This additionally offers support for duck typing, enabling interfaces to be integrated seamlessly in development routines.


4) Scheduler

To prevent blocking operations and to defer them to other threads, Ruby 3 is bundled with a scheduler.


5) Rightward Assignment Statements

Adding the rightward assignment statements is a small but significant change in the way syntax is formulated for Ruby code.

This ultimately enables writing natural-looking code in places where the left assignment looks weird.


6) Better Garbage Collection

By the addition of the Garbage Compactor, objects will be automatically transferred to the heap and compacted to enhance memory usage and performance.


7) Ruby 3 is Fast

Ruby 3 provides us a whole lot faster experience than Ruby 2.7. Ruby is also faster as compared to several other “scripting” languages.


8) Ruby 3 is Easy

With its latest version, you don’t need to fight to get Ruby or a Ruby extension to compile, that was the case with old Ruby. This Ruby 3 employs a fancy-pants version manager like rbenv coupled with Bundler 2.


9) Ruby 3 is Sleek

Ruby is often the best choice when it comes to standard web development. It just makes everything more enjoyable with less code.

Less ceremony, properly object-oriented, and is more streamlined. It makes a more polished and pleasurable reading and writing experience.

10) Ruby 3 is Progressive and Here to Stay 

With the release of Ruby 3, we can look forward to 3.1, 3.2, 3.3, and ahead. This is the start of a whole new era, modern innovations, and new patterns.

Many old-timers are returning and diving into Ruby-based forums and the pace of this new exciting Ruby seems to be increasing.


Final Conclusion:

It’s been almost eight years since Ruby 2.0. There have been a lot of performance changes now in this version of Ruby.

It’s nearly three times the speed of eight years ago Ruby and CPU-intensive code is now solidly three times the speed.

Ruby with its Rails framework is used to be one of the best technologies for start-ups. Ruby 3.0 is great for its:

  • Better concurrency
  • Static type checker
  • Backward compatibility
  • Static analysis
  • Tips for better transmission
