Two of the most popular programming languages, especially first languages, are Ruby and Python. Ruby is used widely for websites such as Airbnb, Hulu, Kickstarter, and Github. Both languages came around in the mids. Python actually predates Ruby by about four years. They both came around to address needs in the programming community, but the philosophies are different.
They both have a lot of different functionality. The thing that unites them is the goal to write clean, readable, concise code. Some languages have specific uses. Another example is SQL, which is a database language. It primarily exists to interact with the database. Keep reading for more in-depth information about Ruby and Python. Language: ex. Python and Ruby. A programming language is a set of rules for giving a computer instructions. Different languages are designed around different philosophies.
There are hundreds if not thousands of programming languages. Interpreter: a program that reads and executes code. Takes your code and allows the computer to run it. Framework: Broader set of tools and techniques built with a language.
Think of a dialect of a language. Different rules for communication, but grounded in the same language. Object-Oriented: a programming paradigm based on the concepts of objects. Dominant philosophy in language design.
Everything in the language is made up of objects that communicate with each other. Both Python and Ruby are Object-Oriented. Functional Programming: a programming paradigm that avoids state changing and mutable data. Python and Ruby blend the two kinds of programming. Language vs. Framework is one of the early ones that gets really confusing.
A lot of languages are object-oriented, but they still have the primitive data type. In Ruby, absolutely everything is an object, meaning everything operates in the same paradigm of sending and receiving messages.
High level, enjoyable, general purpose language spans many industries. You can speak in terms that are more human and less computer.
It has a lot of applications. That means, every programming language is based on other lower level layers of code that make it easy to use. Another level of abstraction is how Ruby programmers use the Ruby programming language to design and build higher level languages called Domain Specific Languages or DSL's like Rails and Rspec.
We do not necessarily need to know how these DSL's are implemented, but we know they exist and know how to use them. As a beginner, you'll have to be aware of these abstractions particularly in programming and computer science and how they simplify programming and make computers easy to use.
It's often confusing, for example, to read Rails or Rspec code without understanding Ruby because Rails and Rspec are DSLs operating at a higher level of abstraction. The goal of this book is to show you Ruby, so that when you come across higher level abstractions and DSLs, you can recognize it as just Ruby code. This book is written for the inexperienced or completely new programmer. If you apply the principles and techniques described in this book, you will build a strong basic knowledge of programming in Ruby.
You may then use this knowledge to continue to learn more advanced concepts. This book will guide you through the common pitfalls and time-sinks that a beginner may experience. It will give you plenty of practice to commit basic Ruby syntax to long-term memory so you can focus on solving real-world problems and building real-world applications.
Being a programmer is often perceived as a difficult task. It is not. It does, however, require a certain temperament. When this temperament is understood and adopted, the work that a programmer does becomes less frustrating, more fun, and quite rewarding.
Perception of the difficulty of a given task is usually inversely proportional to the amount of patience the person attempting the task possesses. If you are patient with yourself and are willing to take the time to work through the exercises and apply the concepts, you will find yourself writing programs and solving problems with code very soon. There is a shift in thinking that will take place and you will develop the ability to think deeply and clearly about a given problem.
This process is often referred to as "flow" and can be very satisfying and engaging. Huge swathes of the Internet are built with Ruby programming language, as are many other applications. But what is the Ruby programming language, and what is Ruby programming used for? Ruby is a scripting language built from the ground up for use in front end and back end web development and similar applications.
It is a robust, dynamically typed, and object-oriented language. More than one person has commented that they could basically understand Ruby code even without knowing how to program! He has stated that the language is designed to be both fun and productive. Python is a programming language that focuses on having a single, unambiguous solution to every problem. Ruby projects, by contrast, want to have many valid approaches to problem-solving.
There are advantages and disadvantages to both methods. Some other differences include how strings are mutable in Ruby but not in Python, and Ruby only has one kind of list container.
However, they are both heavily object-oriented—in both Python and Ruby everything is an object. This can indeed make it much easier to ship code, but means finding deep bugs might require a lot more digging.
Get matched to a bootcamp today. The average bootcamp grad spent less than six months in career transition, from starting a bootcamp to finding their first job. Perhaps most importantly, Ruby is a highly versatile and portable language. Matsumoto was an expert on multiple programming languages at the time, including Perl, Eiffel, Smalltalk, Lisp, and Ada. When creating Ruby, he tried to combine what he thought were the best elements of each of these languages.
There are even large groups of devoted coders that meet in major cities for Ruby-related conferences. Best of all, Ruby is completely free—not only free to use but and open source. It can be copied, modified, and distributed at will. Ruby on Rails revolutionized how web development was done, making it possible to create complex and user-friendly web applications in far less time than before.
Ruby is a highly flexible programming language. Developers coding in Ruby can make changes to the way the language itself works. But unlike Python, which focuses on a single, unambiguous solution for every problem, Ruby projects try to take multiple different approaches to problem-solving.
As you might have guessed, there are benefits and disadvantages to both methods, depending on your project. One feature that makes Ruby so user-friendly is that it hides a lot of details from the programmer. However, it also means that finding bugs in the code can be more difficult. Conveniently, code you write in Ruby will run on any of the major operating systems without having to be ported, including Windows, macOS, and Linux. Ruby has been used in the booking site Airbnb, the streaming service Hulu, and the calorie-tracking app MyFitness Pal.
This fact alone demonstrates just how versatile and powerful Ruby can be. When it comes to web development, the framework Ruby on Rails is used.
