JavaScript错题集：校准事件循环、闭包与原型链的思维偏差

JavaScript核心机制如事件循环、作用域链和原型委托，是前端开发者理解异步行为、变量捕获与对象查找的基础。 其原理不随框架演进而改变——微任务清空时机、词法环境隔离、原型链委托查找等底层规则，始终约束着代码执行逻辑。

深入理解 JavaScript 事件循环（Event Loop）：单线程如何实现非阻塞异步执行

为什么说事件循环是 JavaScript 引擎的核心？ JavaScript 引擎本身是 单线程 的，这意味着同一时刻只能执行一段代码。如果某个操作耗时过长（如网络请求、文件读写、长循环），页面就会卡死。事件循环的存在，让 JavaScript 既能保持单线程的简单模型，又能以 异步、非阻塞 的方式处理耗时任务。
