Course Introduction:Design pattern (Design pattern) is a set of classified and cataloged summary of code design experience that is used repeatedly, known to most people. The purpose of using design patterns is to reuse code, make the code easier to understand by others, and ensure code reliability. There is no doubt that design patterns are win-win for ourselves, others, and the system; design patterns make code writing truly engineering; design patterns are the cornerstone of software engineering, just like the structure of a building.

Course Introduction:JavaScript is a particularly flexible language. In the early years, it was considered a toy-like language that could only do a small job of painting web pages. The project project is not very large, let alone the application of design patterns in Javascript. However, with the rise of Nodejs, HTML5 and web2.0, JavaScript itself has become more and more important. Many classic programming ideas such as design patterns have also been applied to JavaScript to complete larger projects. We have collected "JavaScript Design Patterns Video Tutorial", hoping to help everyone better understand the concept of design patterns.

Course Introduction:Go function error handling modes include: using errors.New() to create errors, wrapping underlying errors, and returning nil to indicate no errors. Anti-patterns include using magic numbers or strings to represent errors, handling errors implicitly, ignoring errors, and delayed exit patterns. Best practice: Use errors.New() to create and return errors. Anti-pattern example: Ignore errors returned by os.Open(). Following best practices and avoiding anti-patterns results in clear, maintainable, and easy-to-debug code.

Course Introduction:Laravel is a popular PHP framework with good scalability and maintainability. However, as the scale of the project expands, various problems and errors will inevitably occur, which requires an in-depth understanding of Laravel's error handling and error reporting modes. Laravel provides a variety of error reporting modes, including development mode (debug mode), production mode (production mode) and maintenance mode (maintenance mode). Each mode has its unique functions and uses.

Course Introduction:Common patterns for handling function errors in Go are: Return error: The function returns an error value, which is nil on success and error type on failure. Global variables: Use global variables to store error values so that functions can easily access and use the error values. Panic: Used when the error is so serious that the function cannot continue to run. The function is terminated immediately and the error is propagated to the caller. Delay: Use the defer statement to execute code before the function returns, suitable for delaying cleanup operations or error handling until the end of the function.
