How do I use Sublime Text with Angular?
Article Introduction:Using SublimeText for Angular development is feasible, but requires manual configuration to improve efficiency. First install Node.js and AngularCLI, and create or run the project through "ngnew" or "ngserve"; open the project root directory in Sublime to access the core file. Then install necessary plugins such as TypeScript, AngularJS, Emmet, LSP-typescript or LSP-eslint to enhance language support and code prompts. Then customize the settings, enable functions such as automatic completion, indentation adjustment, and configure shortcut keys and build systems to execute Angular commands. Finally, use the split screen function at the same time

The Liskov Substitution Principle
Article Introduction:Core points
Liskov Substitution Principle (LSP) is a key concept in object-oriented programming that ensures that subclasses can replace their base class abstractions without breaking the contract with client code. It maintains the integrity of the system design and is crucial to the reusability of the code.
When overriding a method in a subclass, certain requirements must be met: its signature must match the signature of the parent class; its prerequisites must be the same or weaker; its postconditions must be the same or stronger; and exceptions (if any) must be the same as the exception type thrown by the parent class.
Breaking LSP can lead to unintelligible behavior and errors that are difficult to track. It also makes the code harder to maintain and extend, because the assumption that a subclass can replace its superclass is no longer true.
Method rewriting does not always violate LSP

Describe the SOLID principles and how they apply to PHP development.
Article Introduction:The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

What is the SOLID design principles, and how do they apply to PHP development?
Article Introduction:The application of SOLID principle in PHP includes five core points: 1. The single responsibility principle (SRP) requires each class to be responsible for only one task, and improve maintainability through separation functions such as UserService, UserRepository and EmailService; 2. The opening and closing principle (OCP) emphasizes extending openness, modifying closing, and using interfaces or abstract classes to implement new functions without changing old code. For example, the PaymentMethod interface supports multiple payment methods; 3. The Richter replacement principle (LSP) ensures that subclasses can replace parent classes without destroying logic, and avoid behavior abnormalities in the inheritance tree, such as Square should not inherit Rectangle; 4. The interface isolation principle (ISP) advocates dismantling

Can you explain the SOLID principles and how they apply to PHP OOP design?
Article Introduction:SOLID principle improves code maintainability and scalability through five core principles in PHP object-oriented design. 1. The single responsibility principle (SRP) requires that each class has only one responsibility, and the separation of concerns is achieved through splitting functions; 2. The opening and closing principle (OCP) advocates extending behavior through interfaces or combinations rather than modifying the original code; 3. The Richter replacement principle (LSP) ensures that subclasses can replace the parent class without destroying logic and avoid behavior inconsistencies; 4. The interface isolation principle (ISP) recommends defining fine-grained interfaces to avoid redundant dependencies; 5. The dependency inversion principle (DIP) decoupling high-level and underlying modules by relying on abstract types (such as interfaces) rather than concrete implementation, and is commonly implemented by dependency injection.

What are SOLID principles in C ?
Article Introduction:The SOLID principle is five core principles used in object-oriented programming to improve the maintainability and extensibility of software design. ① The single responsibility principle (SRP) requires a class to be responsible for only one task to avoid multifunctional coupling; ② The opening and closing principle (OCP) emphasizes opening and closing of extensions and closing modifications, and implementing behavior expansion through inheritance and polymorphism; ③ The Richter replacement principle (LSP) ensures that subclasses can transparently replace parent classes without changing program accuracy; ④ The interface isolation principle (ISP) advocates defining fine-grained interfaces to avoid unnecessary dependencies; ⑤ The dependency inversion principle (DIP) advocates relying on abstraction rather than concrete implementation, reducing the coupling between modules. These principles can be effectively implemented in C through abstract classes, interface design, dependency injection, etc.

Can you explain the SOLID principles and their application in C# object-oriented design?
Article Introduction:SOLID principle is five design principles to improve code maintainability and scalability in object-oriented programming. They are: 1. The single responsibility principle (SRP) requires that the class only assumes one responsibility, such as separating report generation and email sending; 2. The opening and closing principle (OCP) emphasizes that the extension is supported through interfaces or abstract classes without modifying the original code, such as using the IShape interface to realize area calculation of different graphics; 3. The Richter replacement principle (LSP) requires that the subclass can replace the parent class without destroying logic, such as Square should not mistakenly inherit Rectangle, resulting in abnormal behavior; 4. The interface isolation principle (ISP) advocates the definition of fine-grained interfaces, such as split printing and scanning functions to avoid redundant dependencies; 5.

What is the SOLID design principles, and how do they apply to Python development?
Article Introduction:The SOLID principle is five design principles used in object-oriented programming to improve the readability, flexibility and maintainability of software design, and is also applicable in Python development. 1. The single responsibility principle (SRP) requires a class to do only one thing, avoid putting irrelevant functions in the same class, which can be implemented by splitting logic or using auxiliary modules; 2. The open and closed principle (OCP) emphasizes opening up for extensions, closing down for modifications, and extending functions through inheritance or combination without changing existing code; 3. The Richter replacement principle (LSP) ensures that subclasses can replace parent classes without destroying program behavior, and keep the method contract consistent, avoiding the introduction of exceptions or different return types during rewriting; 4. The interface isolation principle (ISP) advocates defining fine-grained interfaces so that clients only
