Craving more information about Ruby on Rails development? Here's a FAQ for you!

  • What does a Ruby programmer do?

    It’s evident from the name that Ruby programmers are obsessed with the Ruby programming language — so their working projects are primarily Ruby-related. Their tech training and education correspond to their activities: most have graduated from tech universities where they studied applied math, web programming, or something relevant. 

    How to become a Ruby programmer? The first and self-evident answer is — to start learning Ruby (and a couple more languages, they will surely come in handy in the future) — and begin practicing until you feel ready to pursue and secure a job.

    Ruby-proficient web engineers employ Ruby for building new technological products. These skillful programmers can play an instrumental role in various development projects — e.g., designing new web servers, finishing work for API clients, and building static website generators. Moreover, Ruby programmers often have high expertise in other programming languages because this can allow them to complete more complex projects that are impossible to perform using only one language.

    Here’s a list of the most general duties of a Ruby programmer:
    Writing new programs and code chunks using Ruby;
    Creating new program-hosting services;
    Carrying out complete web development on the newly created pages using Ruby;
    Completing web scraping and crawling;
    Uniting Ruby with other programming languages, like C or PHP, to create new computing products;
    Solving problems and maintaining existing infrastructure with the help of Ruby.

  • Does Ruby on Rails use HTML?

    To answer this question, let’s dig into the facts about Ruby programming language and its connection with Rails (and what Rails is).
    Ruby as a programming language was created 20 years ago. Its founding father is Yukihiro “Matz” Matsumoto. In the most ratings, Ruby stays staunch in the top 10 — by large, thanks to the popularity of Rails. Like Java or Python, Ruby is also a general-purpose programming language, though it’s famous for its use in web programming.

    OK, now let’s talk about Rails and how it works with Ruby.

    Rails is a software library that extends the Ruby programming language. Its creator was David Heinemeier Hansson. 
    Technically, Rails is a software code appended to the Ruby programming language or a package library installed via OS command-line interface.

    The critical area of using Rails is website building. Technically, Rails maintains conventions for easier collaboration, codified as the Rails API (application programming interface or directives controlling the code). A programmer learning Rails should learn how to use the Rails conventions and its API.

    The Rails library unites Ruby with HTML, CSS, and JavaScript for creating a web app that runs on a web server. Rails is considered a server-side, or back-end, app development platform (here, the front end is the browser). 
    Rails is not just a library or an API. It’s the major project of a multifaceted community creating software libraries that make the task of building complex websites easier. Members of the Rails community have a lot of common profound values, frequently use the same tools, and support each other with an unofficial network built on volunteerism.

  • How much does a Ruby on Rails developer make?

    Of course, the answers to this question will significantly differ from country to country. The average yearly salary of an American RoR engineer is $79,294 (as of September 2022), or nearly $6500 per month. However, not all the US states are equal, so the salary range typically falls between $71,168 and $88,634 for different locations within the country.
    However, in other regions, the numbers can drastically differ — depending on numerous essential factors, including education level, additional certifications, extra soft and hard skills, and the number of years spent coding.

  • Are Ruby developers in demand?

    Ruby and Ruby on Rails are often shown as an example of IT specialization that was once popular and sparkling and is now almost dying. Is it so — or that’s just a prejudice, even though there’s still a vast RoR demand for MVP coding and development? 

    The core reason for RoR’s decline isn’t its immaturity or incompatibility with everyday tasks but the massive competition in the IT market. When just released, Ruby was a singular framework of a kind and remained in this position before the emergence of new products with similar functionality. 
    The highest point of RoR usage was in 2006. Although its popularity has been slightly declining ever after, it still is one of the most valuable frameworks for web application development. 
    What are the core reasons for RoR criticism, then? Let’s make a brief list.

    1. Slow performance (it’s just a bit slower than other networks, as it frequently happens with interpreted programming languages);

    2. Complicated syntax (one line of Ruby code can perform several different tasks, being somewhat convoluted and complicated to master for juniors);

    3. Problems with scalability (isn’t always an issue of programming language: can be influenced by many programming dysfunctions).

  • Is Ruby on Rails good for a career? 

    RoR has been steadily showing its popularity, incrementing its rating among other programming languages like Python, Java, or C#. Many people prefer RoR, and there’s a good reason why it is so tremendously popular and why Ruby developer compensations are constantly rising. 

    If we classify Ruby, we’d have to say it’s an object-oriented language. What differentiates it from its neighbors is that it resembles human language — so even inexperienced juniors with little to no experience in the field can somewhat understand the code — and it’s an excellent incentive for beginning (just like in Python). 

    Rails is a web development framework for the Ruby language. Like with any other programming language, learning to use it can be tricky and challenging — but becoming an RoR developer is a perfectly justified and intelligent choice.
