## Install

```

npm install get-assigned-identifiers

```

## Usage

```js

var getAssignedIdentifiers = require('get-assigned-identifiers')

var ast = parse(`

  var { a, b: [ c,, ...x ], d } = whatever()

`)

var node = ast.body[0].declarations[0].id

getAssignedIdentifiers(node)

// → [{ name: 'a' }, { name: 'c' }, { name: 'x' }, { name: 'd' }]

```

## API

### `getAssignedIdentifiers(node)`

Return an array of AST Nodes referencing identifiers that are initialised by the `node`, taking into account destructuring.

If `node` is not an identifier or destructuring node, this returns an empty array.
