Naming Is Hard

$3

When looking at this example code...

`ts
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.

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

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`.
