This is an object-oriented language created in 1993. This is an open-source language with a license and is available on the internet. This is used in servers as scripting languages and as a general-purpose programming language. Ruby is used in common gateway scripts and is easily maintainable. It can be embedded into HTML. The syntax is similar to Perl and C++.  Also, it is scalable and is easily maintainable for very big programs.

Why do we need to learn Ruby?

1. Many large projects are written and maintained in Ruby and AWS, Github, Airbnb uses Ruby that still makes the language worthy to learn in this time. Also, its integration with different languages helps the developer to learn the language easily.
2. Several improvements are made to the language every time the language gets updated and hence it makes itself a competitor with Python and many other general-purpose languages.
3. The syntax is simple and readable that helps the language to be used in many startups and different business organizations. Its higher productivity helps to use the language for the faster delivery of results.

Applications of Ruby

• The main purpose of Ruby is to build web applications. Its syntax and coding are developed in a way to build and maintain large web applications.
• The language is used in data analysis, proof of concepts and prototyping like other general-purpose languages. Ruby is used in many development projects due to its simplicity and the way it performs with complex applications.
• A development framework, Ruby on Rails web is developed with Ruby language so that the language helps to develop web applications.
• It can be used in both front end and back end development and hence an all-purpose developing language. The syntax is easy to understand and it is dynamically typed.

Example

Operations in Ruby
# Variables and expressions.

a = 10
b = (3 * a) + 2
printf("%d %d\n", b);

output is 32

Prerequisites

1. Knowledge of object-oriented concepts is good to learn the Ruby language as it is an OOPS language.
2. Database should be known to the developer such as Relational Database, SQL, Postgres or any relational database. This helps to build database knowledge to the developer.
3. Any structural language such as C or C++ is good to know as it helps to develop applications in Ruby.
4. The basic idea of developing web applications or web servers should be known by developers as it helps to maintain the application if the application fails.

Target Audience

The web developers use Ruby for web development and the maintenance of their application as the language is easy to understand and the syntax is simple. The language mostly targets developers who does the web application and create web pages for different applications. Also, the tutorial targets people who want to add Ruby on their profile.
