Naming Is Hard

Terminology

When looking at this example code...

import { a } from './a';
import { b } from 'b';
const c = a + b;
const d = b(c);
export { c };

...we can apply the following (incomplete) list of terms:

| Name | Description | Example | | ------------------ | ------------------------------------------------------- | -------------------------------------------- | | Symbol | Named declaration, connects declaration nodes. | a, b, c, d | | Identifier | Node, references a symbol | a (2x), b (3x), c (2x), d (1x) | | Specifier | More specific classification of identifier | ImportSpecifier a, ExportSpecifier c | | Call expression | Function call with arguments | b(c) | | Import declaration | An import declaration with named and/or default imports | import { b } from 'b' | | Export declaration | An export declaration with named (not default) exports | export { b } from 'b' |

Here is the example code in the TypeScript AST Viewer to see the nodes as described.

Additional terminology

• SourceFile: The AST of a given source file
• Program: Collection of source files, and its main entry

Conventions

The following conventions are used to name the helper functions:

• To get something means the thing is a reference expected to be there (upwards and/or linked).
• To find something means to query for things from a certain starting point (downwards).
• To get things For something expresses an AncestorForDescendant hierarchy.
• To get things Of something means the opposite: descendantOfAncestor.
