An educational diagram illustrating the execution layers of the JavaScript engine. Layout Details:On the left side, a rectangle contains a block of JavaScript code written in a clear, readable font. To the right of the code, a large rectangle labeled "Web API", representing the asynchronous operations handled by the browser. Further right of the Web API, another rectangle labeled "Execution Stacks (Ordered by Priority) " contains four stacked rectangles representing different execution stacks:✅ Call Stack (Topmost layer) console. log () LoopsFunction callbacks✅ Micro Stack (Below Call Stack) PromisesAwait continuationqueueMicrotask✅ Rendering Stack (Below Micro Stack) DOM updatesRendering CSS changesrequestAnimationFrame () ✅ Macro Stack (Bottom-most layer) setTimeout, setIntervalI/O operationsNetwork tasks (e.g., fetch API) To the right of these stacks, a circular arrow symbolizing the Event Loop, labeled "Continuously Checking & Executing Tasks". On the far right, a console output box displaying simulated JavaScript execution results. Color & Styling Preferences:Use soft, readable colors with clear text labels. Differentiate stacks using light shades (e.g., Call Stack in blue, Micro Stack in green, Rendering Stack in orange, Macro Stack in red) . The Event Loop arrow should appear dynamic, visually emphasizing its continuous operation. Why These Enhancements? ✅ Better readability for students 🏫✅ More precise terminology 💡✅ Improved visual clarity 🎨with 4k resolution
一个说明JavaScript引擎执行层的教育图。布局细节：在左侧,一个矩形包含一段以清晰可读的字体编写的JavaScript代码。在代码的右侧,一个标有“”的大矩形；Web API”；,表示浏览器处理的异步操作。在Web API的另一个右边；执行堆栈（按优先级排序）"；包含四个堆叠的矩形,代表不同的执行堆栈：✅ 调用堆栈（最顶层）控制台。log（）循环函数回调✅ 微堆栈（调用堆栈下）Promises等待继续队列微任务✅ 渲染堆栈（微堆栈下）DOM更新渲染CSS更改请求动画帧（）✅ 宏堆栈（最底层）setTimeout
