Member Variables All the member variables are private in Ruby. Member variables in Java have package access by default and may be declared with identifiers i. Ruby class should begin with a capital letter. Class definitions do not have an access modifier in Ruby. A class is defined using the class modifier, which needs to begin with a capital letter.

Program Architecture Project Management. Conclusion Both Java and Ruby are similar and shares a lot of parallel features. At the same time, they both have their own specific features which help with a specific requirement. But definitely, Ruby is not a replacement for Java.

This is basic for awesome developers and a lot are missing that. I've been in the Ruby on Rails game for twenty years. For the last ten, Rails has been declared deceased. The jobs are highly paid and fun. All the pros you list are valid. Yes it is a beautiful language, the OO makes sense, it's dynamic and expressive, and the ecosystem is top shelf.
What's to dislike? There are a lot of Rails websites out there. And new ones get created every day too. Ruby is quirky. Since the syntax is pretty different from PHP, and core developers being opinionated, some people just see drama. When Node. JS got slightly usable, they moved over to that. Many engineering managers will just select the ecosystem that is biggest.
JS is a lot bigger. But if you don't care about going a little off the beaten path sometimes, Ruby in my opinion still, after all this time, gives me joy when I use it.
Also important: to this day, I can build everything I want. Ruby, Rails and many gems are being actively maintained. Security vulnerabilities are discovered and corrected. New developments still find their way into the language. For myself, I know that the anemic JS standard library would just frustrate me to no end Ruby's standard library isn't as voluminous, but it's a lot more diverse and useful.
Java seems to be a good choice, but what other options can I consider that can also be easily scalable as well as a little faster to write?
Firstly, you must know that java and python are both amazing languages. But I recommend python mainly because of the variety of modules and packages available to do almost anything. If you are planning on adding graphs, you can use the matplotlib library and to add photos, use the pillow module. And just note that both of these aren't available by default, so you need to install them through pip. Hi, Kamal! I don't know if your question is still relevant. But I would like to introduce you to our solution, perhaps it will be useful for future projects.
The entire development stack is reduced to SQL only. The platform is easy to configure and make subsequent changes if necessary. I am trying to make Roblox game which requires Lua. I quite don't want to go with Lua just because other tools just might let me do more projects later on. I heard that Python is most similar to Lua, but I am still not sure which tool to use. Java , I think it will help me with many stuff later on for websites, projects, and more! Since you are trying to make a Roblox game, you have no other option than to use Lua, since Roblox only allows coding in Lua.
Yes, you've heard right, Python is identical and as easy as Lua, although Lua is easier than Python. Beginning from Lua and then escalating to Python is recommended. Java is only helpful when you are creating a heavy, big-budget, enterprise-level product, otherwise, Python would suffice. Hi everyone, I have just started to study web development, so I'm very new in this field.
I would like to ask you which tools are most updated and good to use for getting a job in medium-big company. Front-end is basically not changing by time so much as I understood by researching some info , so my question is about back-end tools.
Which backend tools are most updated and requested by medium-big companies I am searching for immediate job possibly? Go with Python definetly. It's used everywhere by web developers for backend developments : API, website backend, workers Java is good but trend is not great in terms of popularity amongs developers and tech leaders.
As per my experience java is most wanted for web development as of now. JavaScript forms the backbone of web development. And, there are many popular and widely used frameworks like Angular and React that heavily rely on the knowledge of JavaScript. The number of job opportunities are much more when it comes to javascript. I would recommend Python as the programming language and as you are a new developer, Flask to start with.
It gives you a solid understanding on the web patterns such as REST and will get you up and running in no time. First grasp the concepts which Python is ideal for then it does not really matter the language as such. Expo was a tool Macombey really wanted to utilize from the beginning. I have been working with React Native since and originally I had to use simulators in Xcode, install pods on top of node packages, configure certificates, and more abundant objectives that take time away from actual development.
As a development studio, we have to move quick and get projects to our clients and partners in a matter of months. Expo made this easy for us.
We now have a mobile app for clients to download and test their project on, there is no need to install pods or configure Xcode, and development is super fast and reliable now.
I had a goal to create the simplest accounting software for Mac and Windows to help small businesses in Canada. This led me to a long 2 years of exploration of the best language that could provide these features:.
When I discovered Javascript, I really knew it was the right language to use. Thinking of this today makes me realize even more how great a decision this has been to learn, use and master Javascript. It has been a fun, challenging and productive road on which I am still satisfied. Obviously, when I refer to Javascript, it is not without implying the vast ecosystem around it.
For me, JS is a whole universe in which almost every imaginable tools exist. It's awesome - for real. Thanks to all the contributors which have made it possible. To be even clearer about how intense I am with Javascript, let's just say that my first passion was music. Until, I find coding with Javascript! Yep, I know! So in conclusion, I chose Javascript because it is versatile, enjoyable, widely used, productive for both desktop softwares and websites with ability to create modern great looking user interfaces assuming HTML and CSS are involved and finally there are job openings.
Python has become the most popular language for machine learning right now since almost all machine learning tools provide service for this language, and it is really to use since it has many build-in objects like Hashtable.
In C, you need to implement everything by yourself. It has many fancy libraries like eigen to help us process matrix. One of Ruby advantages its amazing community gems, that allows to quickly build parts of your systems by merely putting together third party components gets quite complicated to use and maintain in huge applications, where building and reusing your own components may become a better approach.
NET code is far easier to understand, debug and maintain. Although certainly not easier to learn from scratch. Though Rails has an excellent programming speed, C tends to get the upper hand in long term projects. I would avise to stick to rails when building small projects, and switching to C for more long term ones. We have a lot of experience in JavaScript, writing our services in NodeJS allows developers to transition to the back end without any friction, without having to learn a new language.
There is also the option to write services in TypeScript, which adds an expressive type layer. The semi-shared ecosystem between front and back end is nice as well, though specifically NodeJS libraries sometimes suffer in quality, compared to other major languages. As for why we didn't pick the other languages, most of it comes down to "personal preference" and historically grown code bases, but let's do some post-hoc deduction:.
Go is a practical choice, reasonably easy to learn, but until we find performance issues with our NodeJS stack, there is simply no reason to switch. The benefits of using NodeJS so far outweigh those of picking Go. This might change in the future. PHP is a language we're still using in big parts of our system, and are still sometimes writing new code in.
Modern PHP has fixed some of its issues, and probably has the fastest development cycle time, but it suffers around modelling complex asynchronous tasks, and on a personal note lack of support for writing in a functional style. We don't use Python, Elixir or Ruby, mostly because of personal preference and for historic reasons. Rust, though I personally love and use it in my projects, would require us to specifically hire for that, as the learning curve is quite steep.
In other words, we are not willing to pay the price for playing this innovation card. Haskell, as with Rust, I personally adore, but is simply too esoteric for us. There are problem domains where it shines, ours is not one of them. We changed to Python instead of Java to have the back-end processing in the same language as our data analysis module. In addition, Python has a lot of libraries for data-processing. We intend to use Flask for our back-end web development.
Flask is a simple, straight-forward framework for our purposes. Flask also has a large community which is beneficial to the development process. Our team has always been driven by the right tool for the job rather than what we know best.
That said, in balancing practicality we chose to focus on 3 options that our team had deep experience with and knew the pros and cons of. For us it came down to C , JavaScript, and Ruby. At the time we owned our infrastructure, racks in cages, that were all loaded with Windows. We were also at a point that we were using that infrastructure to it's fullest and could not afford additional servers running Linux. That's a long way of saying we decided against Ruby as it doesn't play nice on Windows.
That left us with two options. We went a very unconventional route for deciding between the two. The interfaces were identical and interchangeable.
What we found was easily quantifiable differences. For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was acceptably higher on requests to our Node APIs.
No strong types to protect us from ourselves, but we've rarely found that to be an issue. As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system.
We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities. There is a huge community behind React Native. And one of the best things is Expo. Expo uses React Native to make everything even more and more simple. Awesome technologies.
Some other important thing is that while using React Native, you are reusing all JavaScript knowledge you have in your team. You can move easily a frontend dev to develop mobile applications. A huge PRO of Expo, is that it includes a full building process. You run 1 line in the terminal, and 10 minutes after you have 2 builds done. Double check EAS Expo. C and. Net were obvious choices for us at LiveTiles given our investment in the Microsoft ecosystem. It enabled us to harness of the.
Net framework to build ASP. Coupled with the high productivity of Visual Studio, it's the native tongue of Microsoft technology. In December we successfully flipped around half a billion monthly API requests from our Ruby on Rails application to some new Python 3 applications. Our Head of Engineering has written a great article as to why we decided to transition from Ruby on Rails to Python 3!

Kindly I don't find any help that solve this mystery I need more help if it will happen. Which language should I choose? I use Rust and Java and if you need a compiled language I recommend Rust.
