Ruby Vs. Javascript

Now that we have some information on the two languages, let’s take a look at them and find out which one we could prefer to the other. We will approach this task by comparing them face to face on several fronts.

Typing and Syntax

Ruby is designed for usability. His philosophy is that there is more than one way to do something. So not only does Ruby have simple and easy to learn syntax, but it also has syntax designed to be used however you want. It’s top notch, no variable or semicolon declarations, just easy-to-read code. It is also more object oriented than most other object oriented languages. It is so object oriented that everything is object, with methods and functions, even simple integers. For this reason, programmers can use method chaining; where a lot of code can be reduced to a little bit of code.

JavaScript isn’t terrifying on the eyes, and it’s certainly not as painful to type as C languages, but it just doesn’t look as clean as Ruby. Ruby reads almost like normal human language, placing it high in the high / medium / low level programming chart.

However, since Ruby is so flexible in the way it allows the programmer to use it, it can be difficult to pass code between programmers. Code that would normally consist of multiple lines can be reduced to a few, then down to one line later. While these clean code looks better, it can also be difficult to read or harder to read than the same code spanning multiple lines. a single line of code that should be a lot can be difficult to crack. Because he’s relaxed, Ruby also allows for very inefficient programming methods and doesn’t force anyone to adhere to a set of programming rules, although they should.

Also, since Ruby is at such a high level, debugging can be a nightmare. Ruby is particularly abstract, so figuring out which line of code is manipulating the interpreter the wrong way can be difficult. squo, it’s not as easy as losing a semicolon, and it’s often linked to some invisible interaction happening under the hood, or also buried under a huge call stack

Performance

In general, there is a rule regarding the performance of programming languages. The closer it is to the machine code, the faster it will be. In this sense, the higher a programming language is, the slower it will be. This rule applies to Ruby and JavaScript. JavaScript is not fast, not compared to faster compiled languages ‚Äã‚Äãlike C ++. However, Ruby makes JavaScript look like a Ferrari. For benchmarks, Ruby maintains an average speed 50% to 200% slower than JavaScript (run with node.js). Some things that take less than 30 seconds in JavaScript can take around eight minutes to complete Ruby.

It is important to note that Ruby is slower in a baseline situation. That’s when we throw in something that’s hard to understand and then measure how long it takes the language to understand it. In the real world, when building a web application, you don’t always have to solve Mandelbrot fractals. In this sense, many Ruby fans argue that Ruby is quite fast, only slow compared to other languages, but works fine otherwise. This topic is the subject of intense debate, however, there are many functional examples of Ruby doing well: AirBnB, Kickstarter, or Apple.com to name a few. Performance usually only becomes an issue if perfect timing or large and complex calculations are required.

Both languages ‚Äã‚Äãhave large communities behind them. The JavaScript suite is larger and is considered the most used language by many parameters. It consumes almost 95% of the internet and beyond. In the modules and packages available, he wins for the distance from here to the moon. While Ruby and Rails have a few thousand modules available, npm (for node.js, which is again JavaScript) has over 800,000 modules, most of which are open source and many of which are free for commercial use.

However, since Ruby is a much easier language to use, so is the community. They are generally considered to be helpful and kind to beginners, as Ruby is a kind language to beginners as well. Its community is also very active, which makes it a fairly well documented language. And while the Gem library for Rails isn’t as big as the JavaScript catalog for node.js, the modules are designed with care.

Career perspective

JavaScript rules the internet, and although Rails is easy to use, it lacks the performance or market share of JavaScript. That said, Ruby remains a worthwhile investment for people looking to learn a new language. Ruby also works great as a second language because Ruby is so easy to learn.

At the time of writing, Indeed.com offers more 16,000 ads from I work for Ruby developers and programmers only in the United States. Ruby developers are also making a lot of money. An average Ruby developer can generally expect to make anywhere from $ 50,000 to over $ 200,000 per year. According to Indeed, where all of these jobs are listed, the national average for a Ruby developer in the United States is $ 123,154 per year .

A lot of people will tell you that JavaScript is the best language to have in your pocket, and I don’t think they do. You are wrong. Even if you don’t intend to become a JavaScript specialist, learning JavaScript will likely take you further in the developer’s life, especially as a full stack developer. If you plan on keeping JavaScript the center of attention, that’s not a bad idea either. The same site we used earlier, Indeed, has almost 60,000 JavaScript jobs. On Indeed, the average JavaScript developer salary is similar to Ruby’s: $ 113,615 per year .

Both choices have great prospects, but if you had to choose between the two, JavaScript is the primary language. Unless the internet changes in the next few years, JavaScript is going nowhere and there will always be a need for more JS developers, while Ruby’s future is less certain.
