What is a mixin class in Python?
Article Introduction：The Mixin class is a class in Python that is used to add functionality to other classes but cannot be used independently. Its core purpose is to enhance the behavior of the class by providing reusable methods without forcing the formation of a "is-a" relationship. For example, LogMixin can provide logging capabilities for Database classes, but this is not the primary identity of Database. The best scenarios for using Mixin include: when the code appears repeatedly in multiple unrelated classes, when you want to separate the focus (such as decoupling the log logic from the business logic), and when you need to add non-core optional features. The following steps should be followed when writing Mixin: 1. Create a class that provides only specific methods; 2. It is not expected to be used alone, but combined with other classes

Working with MySQL Events
Article Introduction：Core points
The MySQL event, introduced since MySQL 5.1.6, is a time trigger that can be scheduled for one-time or periodic execution, providing an alternative to scheduled tasks and cron jobs. They can be used to create backups, delete obsolete records, or summarize report data, etc.

What are traits in PHP, and how do they address limitations of single inheritance?
Article Introduction：PHP supports single inheritance, but trait can reuse methods from multiple sources. Trait is a code block containing reusable methods and can be introduced into the class to avoid the problem of multiple inheritance. For example, after defining Loggertrait and being used by the User class, the User class can use the log method. Trait is not an independent class, has no attributes and does not have "is-a" relationship. The way trait solves the single inheritance limit is to allow a class to use multiple traits at the same time, such as DatabaseTrait and LoggerTrait, thereby combining functions. When multiple traits have the same name method, you can specify which method to use insteadof, or use as a method to alias the method to distinguish calls.

How to use localStorage and sessionStorage?
Article Introduction：localStorage is used to store data for a long time, and sessionStorage is used to store temporary during sessions. 1.

Drupal 8 Modules - Configuration Management and the Service Container
Article Introduction：Core points
Drupal 8's ConfigFormBase class provides additional functionality to interact with the configuration system, allowing tools to convert forms to stored values. This can be done by replacing the extension class with ConfigFormBase and making the necessary changes in the form. The configuration in Drupal 8 is stored in a YAML file and can be changed through the UI for deployment across different sites.
The service container in Drupal 8 allows the creation of a service, that is, a PHP class that performs global operations, and registers it into the service container for access. Dependency injection is used to pass objects to other objects, ensuring decoupling. You can create de in the root directory of the module

How to create a private function in PHP?
Article Introduction：A private function is a method defined inside a class and can only be called by that class. In PHP, private functions can be created by using the private keyword, for example: classMyClass{privatefunctionmyPrivateMethod(){echo"Thisaprivatemethod.";}}; Private functions cannot be called directly through object instances, nor can they be inherited by subclasses; common uses include encapsulating internal logic, assisting public methods to complete tasks, and preventing mis-calls; the difference between access modifiers is that public can be called externally, protected allows classes and subclass calls, while private is only limited to

How to Schedule Background Tasks in JavaScript
Article Introduction：Core points
JavaScript is a blocking language that can only perform one task at a time, which can cause long-running scripts to make the browser unresponsive. However, less important background tasks can be scheduled to run without directly affecting the user experience.
requestIdleCallback is an API that allows scheduling of non-essential tasks when the browser is idle, similar to the functionality of requestAnimationFrame. It can be used with the timeout option to ensure that tasks run within a set time range, even if the browser is not idle.
requestIdleCallback is an experimental feature with limited browser support and is not applicable to
