+# is-reference
+
+Utility for determining whether an AST node is a reference.
+
+`foo` is a reference in these cases:
+
+```js
+console.log( foo );
+var foo;
+function foo () {}
+function bar ( foo ) {}
+export { foo as x };
+```
+
+`foo` is *not* a reference in these cases:
+
+```js
+var obj = { foo: 1 };
+console.log( obj.foo );
+export { x as foo };
+```
+
+In all cases, `foo` is an `Identifier` node, but the two kinds must be treated differently for the purposes of scope analysis etc. (The examples are non-exhaustive.)
+
+
+## Installation
+
+```bash
+npm install is-reference
+```
+
+
+## Usage
+
+Example using [Acorn](https://github.com/ternjs/acorn) and [estree-walker](https://github.com/Rich-Harris/estree-walker):
+
+```js
+const { parse } = require( 'acorn' );
+const { walk } = require( 'estree-walker' );
+const isReference = require( 'is-reference' );
+
+const identifiers = [];
+const references = [];
+
+const ast = parse( `var a = b.c;` );
+
+walk( ast, {
+	enter ( node, parent ) {
+		if ( node.type === 'Identifier' ) identifiers.push( node );
+		if ( isReference( node, parent ) ) references.push( node );
+	}
+});
+
+identifiers.forEach( node => console.log( node.name ) ); // a, b, c
+references.forEach( node => console.log( node.name ) ); // a, b
+```
