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.
