Course Introduction:To test page behavior in different time zones in Chrome, there are three ways to do it. 1. Use ChromeDevTools to simulate the time zone: Open DevTools → Click on three points → MoreTools → Sensors, check the overlay option in the DateandTime section and select the target time zone. This setting only takes effect in the current session; 2. Specify the time zone through the command line startup parameters: close all Chrome instances and execute chrome.exe--timezone="target time zone" to affect the entire browser instance; 3. Use JavaScript to overwrite the behavior of the Date object, and the fixed time value is used to accurately control the JS time.

Course Introduction:Efficient code submission: Best practices to avoid future problems Bad code submission can cause huge trouble. Have you ever struggled to pursue the intent of a specific change, or the status of the current code? The correct way to submit code can effectively avoid these difficulties. This article will dive into the best practices of software submission. Core points The correct code submission can prevent confusion and save future time. Submissions should be atomic, dealing with only one specific issue at a time, rather than bloatedly affecting a large number of files and adding multiple features. Good submissions should be clear, insightful and atomic. The commit structure should contain types or components, clear topics, and optional body text to provide more context or details. Problems should be handled in the submission information, using keywords and question IDs

Select variable names that comply with the specifications: use lowercase letters and underscores, do not start with numbers, avoid keywords, and keep them concise and meaningful; 2. Different types such as numbers, strings, lists, Boolean values, etc. can be assigned, and the types are automatically determined by the assigned value; 3. Variables can be reassigned at any time or updated based on the current value, and abbreviation operations such as = and -= are supported; 4. Support one line of code to assign values ??to multiple variables at the same time, and it is necessary to ensure that the number of variables and values ??is consistent.

Course Introduction:In Laravel, duplicate code can be reduced through global middleware and middleware groups. Global middleware is suitable for all requests, such as setting time zones and loading language packs. The registration method is to add class names to the $middleware array of app/Http/Kernel.php, but time-consuming operations should be avoided; middleware groups are used to apply multiple middleware to a set of routes on demand, such as web and API groups, and can be customized and applied to routes, such as authentication and permission judgment middleware to form an admin group, and applied through Route::middleware('admin'); global middleware is selected for system-level operations, and middleware groups are used for business division, thereby improving project structure clarity and maintainability.

Course Introduction:Event loops are the core mechanism of JavaScript asynchronous programming. It cooperates with call stack, message queue and event loop to handle multiple tasks under a single thread. 1. The call stack executes the current task; 2. After the asynchronous operation is completed, the callback enters the message queue; 3. The event loop pushes the callback to the call stack for execution. Macro tasks (such as setTimeout) and micro tasks (such as Promise.then) have different priority: 4. After each event loop, all current micro tasks will be cleared. For example, the output order in the code is Start→End→Promise→Timeout, which means that micro-tasks take precedence over macro-task execution. In actual development, micro-tasks should be avoided indefinite recursion and do not rely on precise time control.

Course Introduction:Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
