术语

🌐 Terminology

绑定

🌐 Binding

在作用域内被赋值/绑定的值。

🌐 A value being assigned/bound within a scope.

装订类型

🌐 Binding type

绑定类型：导入值、赋值（let/const/var）、导出值、函数/类声明、函数/方法参数等。

🌐 The type of the binding: imported value, assigned value (let/const/var), exported value, func/class declaration, func/method arguments, etc.

范围

🌐 Scope

一个可以存在绑定的代码块。代码块是任何被 {} 包围的代码，例如类、函数、方法、回调、if/else 等。作用域有层级关系，父作用域可能有子作用域（不一定），子作用域属于父作用域。如果子作用域中的绑定与父作用域中的绑定同名，子作用域中的绑定会覆盖父作用域中的绑定。

🌐 A block in which bindings can exist. A block is any code surrounded with {}, such as classes, functions, methods, callbacks, if/else, etc. Scopes have a hierarchy, with parents having children (not always), and children belonging to a parent. Bindings in a child shadow those in a parent if they have the same name.

范围标志

🌐 Scope flags

关于当前作用域的元数据（非继承层次作用域）：函数、构造函数、顶层（程序）等。

🌐 Metadata about the current scope (not inherited hierarchy scope): function, constructor, top-level (program), etc.

符号

🌐 Symbol

一个绑定封装器，包含对当前源文本中绑定变量的每个使用/调用位置的引用。符号会按扫描顺序分配一个 ID，每个引用通过该 ID 指向符号。

🌐 A binding wrapper with references to each usage/call site of the bound variable within the current source text. A symbol is assigned an ID in the order they are scanned, and reach reference points to the symbol by that ID.

信号旗

🌐 Symbol flags

有关符号/绑定的元数据。

🌐 Metadata about the symbol/binding.

参考

🌐 Reference

符号引用是符号（进而是绑定）的使用，并按扫描顺序分配一个 ID。每个引用都会被标记为只读、可写或两者兼有。

🌐 A symbol reference is the usage of a symbol (and in turn a binding), and is assigned an ID in the order they are scanned. Each reference is flagged as read, write, or both.

跨度

🌐 Span

节点在源文本中的起始/结束偏移量。

🌐 The start/end offset of the node within the source text.
