Ruby 101 Certification Course

Ruby is a powerful dynamic scripting language used for the completion of huge tasks widely used by developers around the world. This was basically designed as general-purpose scripting language. It's dynamic typing makes it convenient for the interpreters to finish their job in no-time. Tracking and fixing bugs is done thoroughly. In Ruby objects can be modified easily and variable declaration is not an issue as everything here is accessed through objects. It is also case-sensitive. It has a strong framework and supports many virtual studies. Metaprogramming can be done here. Being an open source its data is publicly accessible. Libraries and tools are updated regularly and new features are added regularly which makes it the first preference for our developers to work on projects and code development.

Ruby is technically has a back-end framework. Applications and codes cannot be accessed by user once updated. Most of the data are operated in the back-end of the system. Ruby interacts with application's data. it. It has an amazing framework that completely changes the native behaviour of the language. It has a stock of prewritten codes. Pre-installed features or functions are already present in Ruby for the ease of access especially for developers.

Earlier, functions along with main functions were written. Even now in some languages like C, C++ main function are to be included. In Ruby only the working function is written and with Gems, a pre-installed feature can be used without any hindrance. One can be reliable in this language because of its fast and good productivity.

Ruby is a programming language which can also be used for scripting. It can be used for making web apps as it requires huge codes and implementation. Since compilation is done at runtime i.e, it converts the byte code to machine language at runtime. Browser usually converts the code on the fly into machine code rather than interpreting it. Here, everything is accessed through objects and has an ideal syntax. Being an open source, codes can be edited anytime. It is also portable between different systems in no time. Most of the developers use Ruby scripts for their prototype for web development. Unlike other scripting languages it does not require an interpreter.

It is basically used for web applications, standard libraries and servers in technological companies. It is mainly used in development industry, test automation services, socket programming, bio-medicine computational tasks and many more.

• Development industry: Web developers tend to use Ruby for data-driven and highly efficient web applications.
• Test automation: Ruby controls the execution of text and compares the observed outcome by predicted outcome. This is done in subsequently. Compilation is done at runtime.
• Socket programming: Ruby offers access to network services. Basic socket support can be accessed at low level where clients are allowed to implement both connection and connectionless protocols.
• Bio medicine computational tasks: Data analytics, mathematical modelling and computational simulation is performed using Ruby script.

Ruby requires nothing but knowledge of basic programming language. Since it offers scripting one can get started with Ruby after installation. Coding in Ruby is elementary. It is concise and readable. Strings and arrays can be utilized through objects. Data structure and framework is impeccable. Flow control in ruby is maintained. One can learn to write complex programs and execute them. It has a user input response. You can also learn looping -iterative tasks, arrays - to iterate over data structures, sorting -through blocks for developing algorithms, hashes and symbols for enclosing data structures and object orientation using modules, mixings and method privacy.

Ruby and python has a similar framework but are different in the following ways listed below:

Ruby

• Infinitely flexible empowered for programmers
• Elegant framework eases the programmers to perform tasks instantly
• Tracks down bugs and fixes them promptly
• Compilation is done at runtime
• Focuses just on web development
• Has thousands of libraries but hidden functionality

Python

• Makes direct approach to the programmer
• Less supportive framework than Ruby
• Learning codes and debugging is done efficiently
• Compilation is done by first converting the source code to object code or bytecode, saved and then run 
• Python is used for web and app development. It's easy and readable format simplifies the task for programmers
• It has explicit functionality

Based on performance ruby is much more faster and better than PHP(Hypertext Preprocessor) which is also an open source scripting language and written in HTML. Although PHP is far more popular than Ruby as developers prefer

PHP for writing applications for web development scaling is properly maintained in Ruby. It is convenient to learn ruby than PHP as it handles large software development which requires expertise and is pretty time consuming. Beginners need to understand the basic programming where PHP requires highly skilled developers to perform and complete tasks. Also, runtime is saved in Ruby whereas in PHP compilation is done first where the codes are converted to object code and then the file is set to run.

Ruby is not any programming language that anyone can brag about. Ruby is an interesting and fast language for   app development,because of its efficiency in writing and minimizing tedious time in App production. Ruby has gained much popularity in the past few years and has been ranked as Tiobe's Top 10. It has vigorously evolved because of its framework. It's instant type casting though resembles that of the Python but is quite faster. The trajectory shown in recent rankings have displayed the growth of Ruby in the market. Today Ruby is a great choice for startups.

Ruby is an open source scripting language that uses rails as it is a web application framework. It provides design and support to the language.  Rails asserts Ruby programming language with HTML, CSS, and JavaScript. It is used to a web application that works on a web server. It is because of this fact, rails is formed as the server-side for web development however, the browser is front-end. A repetitive and incremental development framework is vital to the framework. Rails provides ruby with this robust and secure framework. Rails is very different from many web application framework and paradigms.

Ruby on Rails, or Rails, is a dynamic web application framework written in Ruby. it is a MVC( model-view controller),that provide structural database, web services, and web pages. It aids the use of web standards and technical specifications for data transfer and interface. It simplifies huge task required for app development. Ruby o rails can be categorized as software and web development scripts which constitutes software engineering patterns and paradigms.

For example: DRY(Don't Repeat Yourself), Active Record Pattern, Convention Over Configuration etc.

It has introduced many innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development.

Ruby on Rails is a backend programming language. It can store data and offers manipulation of data publicly. The software deals with the business logic for interacting with the data of the application such as Facebook posts, tweets,records. Activities, like writing APIs, creating libraries, and working with system components without user interfaces or even systems of scientific programming, are also included in the backend. Ruby on rails also forms the frontend using various tools or say gems for stylizing.

Ruby on Rails is basically used for app and web development.  It aids the use of web standards and technical specifications for data transfer and interface. Rails provides experts to generate form elemental check-boxes, editing tools, format tools and many more. Implementation of tasks become easier here. Programmers are not asked for compilation as it is automatically done at runtime. It reduces time for the programmers to configure files for setup. It is also used as an API with standard and logical structure.

Ruby on Rails framework helps developers to build websites and applications, because it abstracts and simplifies common repetitive tasks. It helps in stylizing websites and apps. It is written in Ruby. it optimizes Convention over Configuration. It is built on mvc architecture.

The web apps built on Ruby using Ruby on Rails programming language comprise of a well-defined structure, by creating basic divisions between layers, which define routes, controllers, models and bounded views within the framework. This MVC architecture is capable of maintaining and facilitating the decoupling and testing processes. It is not as fast as JAVA but majority of applications are fast enough.

Ruby on rails is a web based application framework. It provides tools to speed up development process and installing gems. It is used for the following reasons: 

• Faster programming with other
• Dynamic frameworks
• Applicable languages
• Object-oriented
• Open source code
• Allows the developers to move between different Rails projects with different structural framework
• Rapid app development helps to accommodate huge data and control changes.
• Easy to read and understand.
• Dynamic typing
• Compilation is done at run-time
• Self-documentation allows the developers to pick up existing projects.
• Good productivity
• Standard framework
• Provides libraries which can be updated regularly
• New features can be added

Though all of these languages are open source. Features are added and updated regularly They differ in the following ways

• Syntax: Django was designed to force a proper indentation, while Ruby was designed to be read and understood just like the English language. It also offers the programmer as much head space as possible. While node.js has a syntax similar to that of JavaScript.
• Purpose: Django is used to perform a variety of  tasks like data science and machine learning while ruby mainly focuses on web and app development. Node.js uses an efficient event-driven non-blocking I/O models infrastructure to build and run an application.
