Regular expressions (regex) are a powerful way to search, match, extract, and replace text in Ruby. Ruby has first-class regex support built right into the language, making text processing concise…
Exceptions are Ruby’s built-in way of handling errors and unexpected situations without crashing your program. Instead of checking every possible failure manually, Ruby lets you rescue exceptions, handle them gracefully,…
Iterators are a core part of Ruby’s expressive style. Instead of writing manual loops, Ruby encourages you to iterate over collections using blocks, making code cleaner, safer, and more readable.…
Ruby makes working with dates and times pleasantly straightforward once you know which class to reach for: Date (calendar dates, no time of day) Time (time of day + timezone/offset,…
Hashes in Ruby are collections of key-value pairs, similar to dictionaries in other programming languages. They allow you to store and retrieve data efficiently using keys. What You’ll Learn 1.…
Ruby is an object-oriented programming language, and everything in Ruby is an object. Classes are blueprints for objects, defining their behavior and attributes. Objects are instances of classes. What You’ll…
Modules in Ruby are a way to group related methods, constants, and classes together. They are similar to classes but cannot be instantiated. Modules are primarily used for namespacing and…
Blocks in Ruby are anonymous chunks of code that can be passed to methods as arguments. They are a powerful feature of Ruby, allowing for concise and flexible code execution.…
