- Object-oriented basics of JavaScript
- JavaScript has grown in popularity in recent years, in part due to the development of libraries that make it easier to create JavaScript applications/effects for those who have not yet fully mastered the core language. While in the past, people generally thought of JavaScript as a basic language and very "sloppy" with no real foundation; this is no longer the case, especially with large-scale web applications and JSON (JavaScript Object Notation) Waiting for the introduction of "adaptation". JavaScript can have all the features offered by an object-oriented language, albeit with some additional work that is beyond the scope of this article. Let's create an object functionmyObjec

- SOLID: Part 4 - Dependency Inversion Principle
- Single responsibility (SRP), open/closed (OCP), Liskov substitution, interface isolation and dependency inversion. Five agile principles that should guide you every time you write code. It would be unfair to tell you that any one SOLID principle is more important than another. However, perhaps none has such a direct and profound impact on your code than the Dependency Inversion Principle, or DIP for short. If you find other principles difficult to grasp or apply, start with this one and then apply the remaining principles to code that already follows the DIP. Definition A. High-level modules should not depend on low-level modules. Both should rely on abstractions. B. Abstraction should not depend on details. The details should depend on the abstraction. This principle was introduced by Robert C. Martin in his "Agile Software

- 6 easy steps to use Twitter's @Anywhere service

- Add spaces between numbers and letters in string using Python
- When working with strings that contain a combination of numbers and letters, it can be useful to insert spaces between the numbers and letters. Adding this space improves the readability and formatting of the string, making it easier to interpret and use. Additionally, we'll explore a technique for doing this using Python. Python provides powerful string manipulation tools, and we will use the re module, which is a built-in module for processing regular expressions. Regular expressions allow us to match and manipulate strings based on specific patterns, making them ideal for solving this task. Additionally, we need to install the re module, which provides the functionality needed to work with regular expressions. If you haven't installed it yet, open a terminal or command prompt and run the following command −xpipinstallr

- Real-time chat using Readline and Socket.io for Node.js
- Node.js has an underappreciated but extremely useful module in its standard library. The Readline module does what it says on the box: reads a line of input from the terminal. This can be used to ask the user a question or two, or create a prompt at the bottom of the screen. In this tutorial, I plan to demonstrate the capabilities of Readline and make a live CLI chat room powered by Socket.io. Not only can the client send simple messages, but it can also send emoticon commands using /me, send private messages using /msg, and allows the use of /nick. A little about Readline This is probably the simplest use of Readline: varreadline=require('re

- How to express spaces in regular expressions
- Regular expression spaces can be represented by "\s", which is a special metacharacter used to match any whitespace characters, including spaces, tabs, newlines, etc. You can also use "\s+" in regular expressions to represent multiple consecutive space characters, and "\S" to represent other characters except space characters. Proficient in these representation methods, you can better apply regular expressions to character String matching and processing.

- A beginner's guide to regular expressions in JavaScript
- Everyone who uses JavaScript has to deal with strings at some point. Sometimes you just store the string in another variable and pass it around. Other times you have to inspect it and see if it contains a specific substring. However, things are not always easy. Sometimes you are not looking for a specific substring, but rather a set of substrings that follow a specific pattern. Suppose you have to replace all occurrences of "Apples" in a string with "apples". You can simply use theMainString.replace("Apples","apples"). Good and easy. Now suppose you also have to

- How to search for a pattern in a string in JavaScript?
- In this article, we will search for a specific pattern and pass only the strings that match the given pattern. We will use the following method to implement this functionality - Method 1 In this method we will search for the string matching the given pattern and get it from the string. string.search() is a built-in method provided by JavaScript for searching strings. We can also pass a regular expression or a normal string in this method. Syntax str.search(expression) Parameter str - defines the string to be compared. Expression - Defines the string expression that will be compared to the string. This will return the index of the string where the string started matching, or "-1" if the string does not match.

- Pattern classes in Java
- The Pattern class represents a compiled version of a regular expression pattern. The Pattern class is located in the java.util.regex package. This class has various methods for various operations such as matching, splitting, searching, etc. In order to create a schema object, use the compile method. Syntax publicstaticPatterncompile(Stringregex) where regex represents a regular expression, which is a string. To compile it we use this method. Additionally, this compiled object can be used to match patterns using the Matcher method. Algorithm To compile and match the pattern, follow these steps - Step 1 - Initialize the regular expression with a string
