执行上下文(Execution Context),一句话概括就是“代码(全局代码,函数代码)执行前进行的准备工作”,也成为“执行上下文环境” 直行JavaScript代码时,但代码执行进入一个环境时,就会为该环境创建一个执行上下文,他会在你运行代码强作一些准备工作,如确定作用域,创建 ...

在AI编程工具Claude Code、Cursor大行其道的今天，开发者常常面临一个“隐形痛点”，随着代码库规模变大，AI 对全局结构的感知能力明显不足。 现有的大模型辅助工具大多只能依赖当前上下文进行即时推理，并不能系统性地理解整个代码库的调用链和依赖关系，这就可能导致遗漏关键上下文，在重构或提交 PR 时出现破坏性错误。而如果我们回到传统的手工方式，一条条翻文件树去理依赖链，效率则低得令人崩溃 ...
