Have you been planning to enhance your skillset by mastering Ruby? Find in-depth resources, study material and problems to practice at Techgig. The specific modules on Ruby are designed to help you learn about each concept in detail. Ruby is a high level programming language empowering programmers to develop precision, bug free and performance oriented programs.

A glance into the extraordinary features of Ruby

Ruby is a lively, insightful, object-oriented as well as general-purpose programming language. It includes a number of versions that include a bunch of additional features. The language's versatility and core competence not only relies on its myriad capabilities, but it also depends on how frequently it is updated. Ruby doesn't disappoint on this account as its various versions keeps on getting updated, which means the language is still growing progressively.

Ruby is a very high-level programming language, which means Ruby handles most of the complex details of the machine. Thus, you can rapidly make impressive software from scratch with less lines of code.

TechGig brings to you a complete tutorial for Ruby Programming which includes most of the important topics starting from Introduction to Basic Data Types, Arrays and Hashes, Enumerables, Methods and Ruby Strings which are almost among the must be trained topics of Ruby programming. As a dynamically formed language, Ruby does not have stringent rules on how to put together features, and it is similar to spoken languages in day to day life.

This tutorial has been arranged for beginners to help out in order to recognize the low-level to high-level concepts related to Ruby Scripting languages. The Ruby Tutorials at TechGig is a detailed tutorial to enable you to study, understand and practice the sample programs until you get the complete hang of it. New programmers will thoroughly enjoy unmasking the various facets of Ruby from the beginning level to the advance stage.

After seeking an adequate amount of knowledge from the Ruby tutorials at TechGig you will find it fun to work with Ruby programming, and it goes without saying enjoyment is an immense motivator when learning to code.

Strings

String objects in Ruby store and process random sequence of one or more bytes, representing the characters that humans understand.

Method

Methods in Ruby denote sets of expressions that return a value. You can organise the code into subroutines inside a method and these can be invoked from different areas of the program. The definition of a method starts with the \'def\' keyword followed by the name of the method. The use of underscore character is to separate words in a method name involving more than one word. The parameters for a method are specified between the parentheses () after the method name and the method definition ends with the \'end\' keyword.

Introduction

Developed in the 1990s, Ruby is a popular programming language because of its flexibility, speed and scalability and the fact that it requires fewer lines of code while working on Ruby. It is a dynamic, object-oriented and general-purpose programming language. The syntax of Ruby is similar to C and Java and the programming language has a short learning curve. Using Ruby, developers can create web applications much faster and using lesser code.

Enumerables

Objects are called enumerables in Ruby when they describe a set of items and a method to traverse over them. The enumerable module in Ruby provides methods like #include, #map, #count, #select, etc.

Arrays and Hashes

Arrays and hashes are used to hold objects of different types. For instance, arrays can contain integers, strings and even floating numbers. Hashes in Ruby use braces instead of square brackets and are similar to arrays. In Ruby, these arrays and hashes are indexed collections that store collection of objects which can be accessed using keys.

Basic Data Type

Data types in Ruby represents different types of data like text, string, numbers, etc. All data types are based on classes because it is a pure Object-Oriented language. There are different data types in Ruby such as Numbers, Boolean, Arrays, Strings, Symbols, and Hashes.
