What is Ruby
Ruby is unique among object-oriented scripting languages. In a sense, it is a purist's language for people who like object-oriented languages. Without exception, everything automatically becomes an object, which is not the case in other programming languages.
#What is an object?
Well, in a sense, you can think of it in terms of building a car. If you have a blueprint, then an object is built from that blueprint. It contains all the properties held by the object (i.e. make, model, color) and the operations it can perform. However, even as a purely object-oriented language, Ruby does not sacrifice any usability or flexibility by omitting features that are not explicitly related to object-oriented programming.
Ruby's architect Yukihiro Matsumoto (known simply as "Matz" online) designed the language to be simple enough for beginning programmers to use, yet powerful enough to give experienced programmers everything they need. tool. It sounds contradictory, but this dichotomy is due to Ruby's pure object-oriented design and Matz's careful selection of features from other languages, such as Perl, Smalltalk, and Lisp.
There are libraries for building all types of applications with Ruby: XML parsers, GUI bindings, network protocols, game libraries, etc. Ruby programmers also have access to powerful RubyGems programs. Compared to Perl's CPAN, RubyGems makes it easy to import other programmers' libraries into your own programs.

In-depth analysis of the similarities and differences between Golang and Ruby
Jun 01, 2024 pm 08:46 PM
The main difference between Go and Ruby is that Go is a statically typed compiled language that supports lightweight parallelism and efficient memory management, and is suitable for writing high-concurrency applications; Ruby is a dynamically typed interpreted language that supports true parallelism but memory management It requires manual control and is suitable for writing flexible web applications.

Why have Python, Ruby and other languages deprecated the increment operator?
May 11, 2023 pm 04:37 PM
Many people may notice a phenomenon, that is, in some modern programming languages (of course, not referring to "recent" programming languages), the increment and decrement operators have been cancelled. In other words, there is no such expression as i++ or j-- in these languages, but only i+=1 or j-=1 Such an expression. This answer will explore the background and reasons for this phenomenon from the perspective of design philosophy. Strictly speaking, it may be biased to say "i++ is disappearing", because it seems that only Python, Rust and Swift among mainstream programming languages do not support the increment and decrement operators. When I first came into contact with Python, this was also
How to implement a simple data conversion function using MySQL and Ruby

How to use MySQL and Ruby to implement a simple data conversion function. In actual development work, data conversion is often required to convert one data format into another data format. This article will introduce how to use MySQL and Ruby to implement a simple data conversion function, and provide specific code examples. First, we need to install and configure the MySQL and Ruby environments. Make sure you have a MySQL database installed and can connect to the database via the command line or other tools. In addition, you need to install
How to implement a simple asynchronous task scheduling function using MySQL and Ruby
Sep 20, 2023 am 10:48 AM
How to use MySQL and Ruby to implement a simple asynchronous task scheduling function. Most of the previous web applications used a synchronous method to process requests, that is, after the user sends a request, the server will immediately process the request and return the result. However, as the complexity of applications increases, the processing efficiency of synchronous methods gradually becomes inefficient, so asynchronous task scheduling has become a common requirement in modern web applications. This article will introduce how to use MySQL and Ruby to implement a simple asynchronous task scheduling function, including task
