The steps to build a Laravel environment on different operating systems are as follows: 1.Windows: Use XAMPP to install PHP and Composer, configure environment variables, and install Laravel. 2.Mac: Use Homebrew to install PHP and Composer and install Laravel. 3.Linux: Use Ubuntu to update the system, install PHP and Composer, and install Laravel. The specific commands and paths of each system are different, but the core steps are consistent to ensure the smooth construction of the Laravel development environment.

In VSCode, you can use Git for code version fallback. 1. Use gitreset--hardHEAD~1 to fall back to the previous version. 2. Use gitreset--hard to fall back to a specific commit. 3. Use gitrevert to safely fall back without changing history.

Configuring the Ruby development environment in VSCode requires the following steps: 1. Install Ruby: Download and install from the official website or using RubyInstaller. 2. Install the plug-in: Install CodeRunner and Ruby plug-ins in VSCode. 3. Set up the debugging environment: Install the DebuggerforRuby plug-in and create a launch.json file in the .vscode folder for configuration. This way, you can write, run, and debug Ruby code efficiently in VSCode.

The steps to manually install the plug-in package in VSCode are: 1. Download the .vsix file of the plug-in; 2. Open VSCode and press Ctrl Shift P (Windows/Linux) or Cmd Shift P (Mac) to call up the command panel; 3. Enter and select Extensions:InstallfromVSIX..., then select .vsix file and install. Manually installing plug-ins provides a flexible way to install, especially when the network is restricted or the plug-in market is unavailable, but attention needs to be paid to file security and possible dependencies.

Configuring VSCode to synchronize code with GitHub can improve development efficiency and team collaboration. First, install the "GitHubPullRequestsandIssues" and "GitLens" plugins; second, configure the GitHub account; then clone or create a repository; finally, submit and push the code to GitHub.

Best practices for writing JavaScript code in VSCode include: 1) Install Prettier, ESLint, and JavaScript (ES6) codesnippets extensions, 2) Configure launch.json files for debugging, and 3) Use modern JavaScript features and optimization loops to improve performance. With these settings and tricks, you can develop JavaScript code more efficiently in VSCode.

I have a lot of experience in participating in VSCode offline technology exchange activities, and my main gains include sharing of plug-in development, practical demonstrations and communication with other developers. 1. Sharing of plug-in development: I learned how to use VSCode's plug-in API to improve development efficiency, such as automatic formatting and static analysis plug-ins. 2. Practical demonstration: I learned how to use VSCode for remote development and realized its flexibility and scalability. 3. Communicate with developers: I have obtained skills to optimize VSCode startup speed, such as reducing the number of plug-ins loaded at startup and managing the plug-in loading order. In short, this event has benefited me a lot and I highly recommend those who are interested in VSCode to participate.

VSCode solves the problems of multilingual project coding and garbled code including: 1. Ensure that the file is saved with correct encoding and use the "redetection encoding" function; 2. Set the file encoding to UTF-8 and automatically detect the encoding; 3. Control whether to add BOM; 4. Use the "EncodingConverter" plug-in to convert encoding; 5. Use the multiple workspace functions to set encoding for different sub-projects; 6. Optimize performance and ignore unnecessary file monitoring. Through these steps, the coding problem of multilingual projects can be effectively dealt with.
