What is Crystal Programming Language? Know Everything

Crystal Programming Language is an object-oriented programming language that aims to bring C-like functionality into very abstract web development. The syntax is largely inspired by Ruby, with the added advantage being a lower learning curve for Ruby developers.

Crystal depends on LLVM for creating native code, thus making use of all the optimizations included in the toolchain. Additionally, it is type-checked, meaning that any error that occurs will be identified earlier, rather than failing during time off.

The language has macro-systems and can support operator overloading as well as automated garbage collections. Its syntax is designed to quickly call native libraries, which means that there is no need to implement low-level tasks. Furthermore, it utilizes green threads, also known as fibers, to ensure the goal of concurrency.

Crystal is currently in the stage of development. There are a few brave people who have begun using Crystal in their production lines, including Neopoly GmbH, Appmonit, Bulutfon, and Protel.

What are the reasons to learn Crystal Programming Language?

If a developer is wondering whether it is worth learning the Crystal programming language worthwhile to learn, it is, yes. And if you’re beginning your journey as a Ruby developer, there’s no debate about whether or not it is worthwhile to explore Crystal, and its learning process is very effortless.

If that’s not the scenario, here are the number of reasons to look into Crystal worth learning about:

It will require less code. Since Crystal is a simple syntax and doesn’t contain garbage code, you’ll spend less time writing code than, say, using C.

Many of its functions are in line with the features of other languages, as Crystal is a re-written blend from Ruby as well as C. This means that you’ll have laid the foundations to learn these languages, too.

It is possible to use Ruby materials as a basis for Crystal. Although the programming language itself doesn’t have documentation, since it has a lot in common with Ruby, you can also utilize common learning resources.

However, it’s essential to keep in mind that Crystal does not have solid documentation; therefore, it can be difficult for developers who have no C or Ruby basic knowledge to acquire.

Advantages of Crystal Programming Language

Crystal has blended the strengths of more than a handful of programming languages. This allowed developers to write flexible, readable but also highly-performing code.

Here are the significant benefits of crystal:

  • Compiled – developers are able to catch many code mistakes by running the code through an editor. Instead of deploying the entire repository in one go, Crystal developers will be able to distribute binaries.
  • It enforces the use of types – unlike most of its rivals (Java, PHP, Python), Crystal allows developers to define type definitions, allows union types, and type checking. This is one of Crystal’s best features since it lets developers maintain a well-structured code.
  • It is fast – Crystal developers have used C as an example and have worked to make Crystal and Amber the web framework nearly as quick. It is a lot more efficient than Ruby and is among the few languages in which an easy syntax can be successfully coupled with speed performance.
  • the Crystal enables macros to support – It allows meta-programming (though only at the compilation stage). While macros can be challenging to navigate, programmers have easily implemented this concept. Getting a knack for Crystal macros shouldn’t be too tricky for even novice software engineers.

Disadvantages of Crystal Programming Language

After listing all the benefits of Crystal, it appears flawless – quick, well-compiled with stunning syntax with meta-programming functionality. In reality, However, Crystal still has issues and drawbacks that stem from only a few years in use.

Here are the significant negatives of Crystal:

  • Insufficient Windows compatibility – Though there are methods for you to use Crystal programming languages on Windows OS by using ports or Linux emulators, this is not native compatibility. If you choose to use Crystal will mean you’re likely to be obligatory to choose Linux as your primary OS.
  • The absence of development tools – Since the Crystal user base is young, The language is not well-equipped on the level of library libraries and other tools. It is also more challenging to learn Crystal as a beginner programming language and reduces the pool of developers who are able to master the art of it.
  • Problems with communication – A different challenge that the Crystal community constantly has to deal with is communication. Since the company behind Crystal is a small technology company located in Argentina isn’t capable of committing a lot of money or time to support the community in the same way that Google is, for instance, has done with its GoLang.
  • The lack of widespread acceptance limits the number of situations developers can get tips from. Developers who are eager to launch developing a project in Crystal are among the early adopters of the language. 

Crystal VS Rust

Crystal is fast in a similar way as the C programing language and is as elegant as the Ruby programming language. It is a programming language that is similar to Ruby. However, it compiles to native code and tries to be more efficient but at the cost of not allowing certain dynamic features of Ruby.

Rust is a secure, functional, concurrent, and available language. Rust is a systems-oriented programming language that provides solid compile-time accuracy and speedy performance. It enhances the concepts of other languages for systems like C++ by providing absolute memory security and total control over the life cycle of memory.

Crystal VS Ruby

  • There’s no reason to run the compiler every time developers want to test their code. It’s a routine process for a Ruby developer and an exhausting one since it slows up the development process significantly. Because Crystal is written in a compiled mode and is a compiled language, it’s not necessary to devote a lot of time to executing code blocks.
  • Crystal developers must pay greater attention to lower-level components. It’s a trait that it shares with C instead of Ruby. Although it may be daunting and time-consuming initially it’s something Crystal developers can’t get to get around.
  • Macros instead of reflection. As mentioned previously, Crystal can be meta-programmed using macros, whereas Ruby could reflect. Through macros, users will have the ability to automatically generate code during the development phase in the latter stages. Since both are highly useful, it’s hard to decide which one is superior.
  • The source code of the language is created in Crystal coding language. In Ruby instead, more than 30% percent of all code has been written using C. But crystal is more efficient this way since it allows developers to comprehend the language’s source code nearly completely.

Crystal VS C

  • Crystal is more precise concerning syntax. The code writes scores higher in readability and tightness in comparison to C. Additionally, With Crystal, developers can generally eliminate redundant code because, unlike C Crystal, it allows garbage collection.
  • Crystal has a less arduous learning curve. C is viewed as one of the most challenging languages for programmers to master. It’s also not simple to comprehend as well as maintain code. Because of its Ruby-like syntax, Crystal appears more familiar to a beginner developer.
  • There is a built-in binding for C libraries that developers can benefit from without writing one piece of code.
  • There isn’t a wider acceptance. It’s important to recognize that Crystal could eventually lose the same speed as C for speed once the language expands and develops. At present, Crystal lacks the range of usage and is less stable than Python, demonstrating its reliability.


Crystal is a strong yet brand-new programming language that, even though it was recently launched, has gained popularity with developers and appears to be capable of competing with Python, C, and Ruby to be a frontrunner on the market.

However, the Crystal programming language still has a long way to go. Considering the language creators aren’t funded sufficiently to compete with older competitors with the help of promotion and advertising, It’s unclear how long the language will last. If it is, Crystal is worth betting on and is likely to become an excellent platform for the development of large-scale products shortly.
