Finding out a new programming language can open up your head in techniques you hardly ever assumed achievable. Just like discovering a new human language like Spanish or Mandarin, you discover to think with various words and phrases and constructions.
You tap into the cultures and communities of the speakers and learn how they see the globe. It’s enriching, to say the the very least.
The neat point about programming languages is that the 1st just one you learn is often the toughest. As soon as you comprehend simple structures like if-clauses and for-loops, you will see them popping up in several new languages you may possibly discover.

And, contrary to human languages, new programming languages are significantly faster to master. They are extra rational and have considerably less text — or, ought to I say, commands.
It follows that most programmers and facts scientists grasp far more than 1 programming language.
They could possibly have a major or favorite a person. But most application builders I know use at least 5 languages on a weekly basis, if you count scripting languages in.
Most programmers also consider to find out a new language every single so normally.
It will come with the job. Coding implies staying curious.
The case for Crystal
Crystal, as for each its ad, is a language which is speedy like C and slick like Ruby.
The component about its slickness is true. It’s compiled and statically typed, which will come with its personal strengths and negatives. Previously mentioned all, even so, it’s quite equivalent to Ruby in its type.
Personally I’ve under no circumstances written a bigger undertaking in Ruby. But as a fairly skilled Python developer, Crystal code nevertheless seems crystal distinct!
Here’s an case in point of a recursive loop that calculates factorials:
The command places seems a bit odd to people who aren’t accustomed to Ruby. It is mainly a terrible-style version of print in other languages. There are some refined discrepancies concerning places and print but we won’t dive into these listed here.
Apart from that, this instance appears to be really pythonic, proper?
It’s similar for if-clauses:
Aside from the funny puts expression that non-Ruby-natives aren’t employed to, this is all over again quite readable.
Usually talking, the syntax of Crystal is obvious, even when dealing with much larger and much more complex complications.
Crystal is statically typed, but you may possibly have discovered there weren’t several form identifiers in the illustrations earlier mentioned. Which is due to the fact Crystal only involves you to specify the variety of a variable if it’s ambiguous.
This apply, of study course, allows programmers be much more productive.
Statically typed languages tend to be finicky all-around macros. Crystal, on the other hand, has a way with them.
As proven in this example, you can use a Crystal macro to alter a piece of code at compile time as a result of static reasoning, dependent on the contents of a further piece of that identical code. Try out to do this in C++ and you’ll both fall short or have to have 500+ lines of code.
Or really don’t you, you genius? Allow me know if I’m wrong…
This does appear with some caveats since, as the expressing goes, with good electrical power will come fantastic responsibility. Static typing generally reduces some danger, but insanely powerful things (like the ones that Crystal permits) to some degree undo this safeguarding.
Talking of basic safety, Crystal does have more safeguards somewhere else. Nil is a different kind for the Crystal compiler. So if you are hoping to entry a process or container that turns out to be nil, the compiler will alert you. This could outcome in a failure of compilation, but at least you get to correct the mistake ahead of you operate a potentially big code.
No extra dependency hell
If you’ve at any time handled a substantial challenge in Python, you likely know what dependency hell looks like.
A person Python module may well depend on another number of, and once you’ve imported all the modules you will need, you recognize that various module versions are not compatible. Now you have to figure out which variations to use to make everything suit together, and all of this can consider hours when your project is of a sure dimensions.
In Crystal, these modules are termed shards, and they get compiled into your binary executable via static linking. I could go into element about this, but let us minimize the story short: Dependency management is significantly, significantly simpler this way.
The big disadvantage: Crystal is little
Crystal had a second in 2017 when it jumped from spot 60 to 32 on the TIOBE index within just just a month. The causes for this meteoric increase are tough to say, but it is fairly likely that the creators of Crystal did significant marketing and advertising at the time and acquired Ruby programmers curious.
Nonetheless, Crystal’s instant of fame did not very last really lengthy. At the time of producing this posting, Crystal is nowhere near to the top 50 programming languages on the TIOBE index.
Because of its early rise in attractiveness, some people today hoped it could see related stages of reputation as Rust.
This, however, hasn’t materialized.
Programmers have expressed irritation about sample jobs or code bases. Also, the documentation seems a small bit incomplete. This turned new programmers off in droves.
And for the reason that of this, the Crystal community is so modest that you will have to wait a though to get assistance if you are running into troubles. There just are not so several answers on StackOverflow, GitHub, and the likes.
The other drawback: Crystal is not as fast as promised
The creators of Crystal wanted the language to be as rapid as C.
This could be real in isolated situations. Nevertheless, most of the time, Crystal can take about twice as lengthy to execute as C does.
It is not uncommon for programming languages (or tech providers, for that make a difference) to have overblown mission statements. And, to be honest, fifty percent as rapidly as C is however fairly rapidly.
Nevertheless, Crystal substantially beneath-provides vis-à-vis its first assure. It’s so glaringly clear that I just can’t blame the typical developer for feeling dissatisfied.
Popular last terms: Crystal is for skilled programmers only
I like checking out new programming languages, but I want properly-documented languages with a significant and supportive community. Quite a few programmers truly feel similar.
Crystal has experienced its shot at mainstream enchantment, but all round it has unsuccessful in the very last few yrs.
This does not necessarily mean that there aren’t some interesting use instances for Crystal. It may be an interesting alternative for individuals functioning with blockchain engineering. You can make a quite strong cryptocurrency with Crystal.
That staying explained, except if the documentation, internet marketing, and normal group aid for Crystal improves, it will not be a good option for the ordinary blockchain developer possibly.
If you want to perform with a language like Crystal, you’d much better deliver some expertise. For the reason that when you’re confronted with a challenge, there could be no person there to aid you.
