Article Introduction：This article discusses how to use JavaScript/TypeScript for code conversion in SWC. Although there is currently no official JS/TS plug-in API, by deeply understanding and manipulating abstract syntax tree (AST), developers can use the parse and transform methods of the @swc/core library to insert custom logic between code parsing and generation to achieve flexible code conversion requirements. The article will use specific examples to demonstrate how to modify AST nodes to achieve the expected conversion effect, providing practical guidance for developers who want to optimize JS/TS code in the SWC ecosystem.

Article Introduction：In PHP, the main difference between == and == is the strictness of type checking. ==Type conversion will be performed before comparison, for example, 5=="5" returns true, and ===Request that the value and type are the same before true will be returned, for example, 5==="5" returns false. In usage scenarios, === is more secure and should be used first, and == is only used when type conversion is required.

Article Introduction：When developing a Geographic Information System (GIS), I encountered a difficult problem: how to efficiently handle various geographic data formats such as WKT, WKB, GeoJSON, etc. in PHP. I've tried multiple methods, but none of them can effectively solve the conversion and operational issues between these formats. Finally, I found the GeoPHP library, which easily integrates through Composer, and it completely solved my troubles.

Article Introduction：This article aims to illustrate best practices for handling dates and times in applications, especially when passing time information between the UI and the backend. The core idea is to stick to the use of UTC as a common standard for data storage and exchange, and to perform time zone conversion only when user interface display or specific business logic requires it. This article will dive into how to achieve this using the Instant and ZonedDateTime classes in the java.time library, and emphasizes avoiding fuzzy time zone abbreviations.

Article Introduction：Using === instead of == is the key to avoiding the PHP type conversion trap, because === compares values and types at the same time, and == performs type conversion to lead to unexpected results. 1.==The conversion will be automatically performed when the types are different. For example, 'hello' is converted to 0, so 0=='hello' is true; 2.====The value and type are required to be the same, avoiding such problems; 3. When dealing with strpos() return value or distinguishing between false, 0, '', null, ===; 4. Although == can be used for user input comparison and other scenarios, explicit type conversion should be given priority and ===; 5. The best practice is to use === by default, avoid implicit conversion rules that rely on == to ensure that the code behavior is consistent and reliable.

Article Introduction：To create a responsive image comparison slider, you must first build an HTML structure containing the front and back images and separation bars; 2. Use CSS to set relative units and object-fit to ensure layout adaptability; 3. Control the display range of the "before contrast" pictures through width or clip-path; 4. Add JavaScript to achieve sliding interaction between mouse and touch events; 5. Optimize styles for mobile devices and ensure touch support, and finally realize a responsive image comparison function that does not require a third-party library, is compatible with modern browsers, and fully supports desktop and mobile user interaction.

Article Introduction：In PHP, the main difference between == and == is the strictness of type checking. The == operator performs type conversion when comparing, while === strictly checks the values ??and types without conversion. For example: "5"==5 returns true but "5"==5 returns false; 0==false is true but 0===false is false; null===0 is always false. You should use == when the type is independent or requires flexible comparison, such as user input processing; if the type must be consistent, such as the detection function returns false, validation null or boolean flag. It is recommended to use === first to avoid logic caused by type conversion

Article Introduction：To use PHP to implement AI image style conversion, you need to follow the following steps: 1. Select a suitable AI model, such as CycleGAN or StyleTransfer, and you can use the trained model or train it yourself; 2. Deploy the model to the server, such as TensorFlowServing or TorchServe; 3. PHP calls the AI model and execute it through shell_exec or Symfony/Process components; 4. Use GD library or Imagick extension to perform image preprocessing; 5. Color adjustment, sharpening and other post-processing of the conversion results; 6. Display the results through HTML, CSS, and JavaScript. PHP acts as a bridge and is responsible for connecting

Article Introduction：The difference between == and == in PHP is that: == is a loose comparison, only the values ??are compared and type conversion is performed, for example, 0=="0" is true; while === is a strict comparison, which compares both values ??and types, such as 0==="0" is false. Common type conversion rules include converting a string to a number when compared to a number, converting a Boolean value to 0 or 1, etc. It is recommended to use === first to avoid unexpected errors. For example, when checking the return value of strpos(), you must use === to determine whether it is false.

Article Introduction：This article discusses the reasons for the duplication of code in the Go language standard library image package (such as the Opaque() method). The core lies in Go's type system's strict restrictions on conversion between different slice types of underlying memory representations, and even if the logic is the same, it cannot be directly abstracted. This leads to a specific type of implementation that has to be adopted to maintain high performance, while pointing to the challenge of lack of a general solution before Go introduced generics.

Article Introduction：The method to quickly measure the distance between two points in AutoCAD is to use the "Distance" command (DI), click the starting point and end point to display the values, but pay attention to unit settings, capture opening and coordinate system accuracy. If the object is an arc or polyline, it can be decomposed and measured one by one or viewed through the "Properties Panel". For continuous paths, it is recommended to use "Polyline Edit" to merge the line segments and view the total length, or use the "Measure Path" function to track the accumulated distance in real time. Issues that are easy to ignore during measurement include: coordinate system deviation, endpoint capture not enabled, unit conversion errors and viewport proportional influence. It is recommended to operate in the model space to ensure accuracy.

Article Introduction：PHP input validation using a do-while loop ensures that input prompts are executed at least once and requests are repeated when the input is invalid, suitable for command-line scripts or interactive processes. 1. When verifying the input of numerical values, the loop will continue to prompt until the user enters a number between 1 and 10. 2. When verifying strings (such as mailboxes), remove spaces through trim() and use filter_var() to check the validity of the format. 3. The menu is selected to ensure that the user enters valid options between 1-3. Key tips include: using trim() to clean input, reasonable type conversion, provide clear error information, and avoid infinite loops. This approach is suitable for CLI environments, but is usually replaced by frameworks or one-time validation in web forms. therefore,
