Intermediate Ruby Programming and Control Structures

In this module, we will delve into the intricacies of handling strings in Ruby. You will learn the differences between single and double quotes, how to create multiline strings with here documents, and perform string comparisons using equality and inequality operators. We'll explore different methods for concatenation, understand indexing to access and modify string characters, and apply various string methods like 'length', 'empty'?, 'capitalize', 'reverse', and bang methods for mutating strings directly.

In this module, we will explore various looping constructs in Ruby. You will learn the syntax and usage of the 'while' and 'until' loops, understanding how they execute based on conditional statements. We will tackle the FizzBuzz problem, a popular beginner coding challenge, and walk through its solution. Additionally, we will introduce control flow keywords such as 'next' and 'break', and delve into recursion, where methods call themselves to solve problems.

In this module, we will focus on debugging techniques in Ruby. You will learn to import and use the debug library to establish breakpoints with 'debugger' or 'binding.break', allowing you to pause execution and examine the program's state. We will cover the 'step' keyword to progress through code line by line and demonstrate how to use the 'info' keyword to list all variables and parameters.

In this module, we will introduce you to arrays, a fundamental data structure in Ruby for storing ordered elements. You will learn how to create arrays, including nested arrays for multidimensional data structures. We'll cover different ways to access and overwrite array elements using square bracket syntax, the 'fetch' method, and methods like 'first', 'last', and 'values_at'.

In this module, we will explore ranges in Ruby, an object that represents a sequence of numbers or letters. You'll learn to create numeric and alphabetical ranges and understand the rules of inclusivity and exclusivity using two and three dots. We will cover methods like 'include'? and 'member'? to check if a value exists within a range, and use the 'rand' method to generate random numbers.

In this module, we will dive deeper into array operations, focusing on iteration and advanced methods. You will learn to use the 'each' and 'each_with_index' methods for sequential element traversal, and how to nest 'each' method calls for more complex operations. We'll explore using traditional 'for' loops and alternatives like 'while' and 'until' loops for array iteration.

In this module, we will continue exploring advanced string manipulation techniques in Ruby. You will learn to use the 'split' method to divide strings into arrays based on specified delimiters and the 'join' method to merge array elements back into a single string. We will cover iterating over string characters with the 'chars' and 'each_char' methods, and converting strings to arrays for iteration.

In this module, we will explore how object references and copies work in Ruby. We will then cover the 'dup' and 'clone' methods, which create copies of objects, isolating them from changes made to the source object. The 'freeze' method will be introduced to make objects immutable, ensuring their state cannot be altered.

In this module, we will introduce you to hashes, a versatile data structure for associating keys with values. You will learn how to create and manipulate hashes using various syntaxes, including hash rockets and shorthand notations with symbols as keys. We will cover methods for adding, iterating over, and checking the inclusion of key-value pairs, as well as extracting subsets, converting between hashes and arrays, and removing pairs.

In this module, we will explore advanced array methods that provide powerful ways to manipulate and transform arrays in Ruby. You'll learn to reverse and sort arrays, remove duplicates with 'uniq', and eliminate 'nil' values using 'compact'. We will cover aggregation methods like 'inject' and 'reduce', as well as methods to flatten nested arrays.
