Course Introduction:Go can be compiled into WebAssembly to run in the browser, achieving efficient interaction with JavaScript, and is suitable for scenarios such as high-performance computing. The specific steps include: 1. Set up GOOS and GOARCH and compile and generate .wasm files; 2. Use wasm_exec.js to bridge Go and JS environment and load and execute in HTML; 3. Use the syscall/js package to realize Go calling JS functions and registering functions for JS calls; 4. Applicable to high-performance demand scenarios such as audio and video encoding, existing Go back-end multiplexing, encryption operations, and cross-platform toolchain.

Course Introduction:The core reason why browsers restrict the automatic playback of HTML5 videos is to improve the user experience and prevent unauthorized sound playback and resource consumption. The main strategies include: 1. When there is no user interaction, audio automatic playback is prohibited by default; 2. Allow mute automatic playback; 3. Audio videos must be played after the user clicks. The methods to achieve compatibility include: setting muted properties, mute first and then play in JS, and waiting for user interaction before playing. Browsers such as Chrome and Safari perform slightly differently on this strategy, but the overall trend is consistent. Developers can optimize the experience by first mute playback and provide an unmute button, monitoring user clicks, and handling playback exceptions. These restrictions are particularly strict on mobile devices, with the aim of avoiding unexpected traffic consumption and multiple videos

Course Introduction:WebWorkers is a multi-threaded mechanism provided by the browser, which is used to place time-consuming tasks on the background thread to execute, avoiding blocking the main thread. 1. Worker does not have DOM operation permissions, and can only pass messages through postMessage and onmessage; 2. Creating a Worker requires a separate JS file and instantiated through newWorker(); 3. Common uses include data processing, image audio processing, JSON parsing, game AI computing, etc.; 4. Pay attention to cross-domain restrictions, resource consumption control and compatibility issues when using it. The rational use of WebWorkers can significantly improve web page performance and user experience.

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.
