/**
* Produces a JavaScript value given a GraphQL Value AST.
*
* Because no GraphQL type is provided, the returned JavaScript value reflects
* the provided GraphQL value AST.
*
* | GraphQL Value | JavaScript Value |
* | -------------------- | ---------------- |
* | Input Object | Object |
* | List | Array |
* | Boolean | Boolean |
* | String / Enum | String |
* | Int / Float | Number |
* | Null | null |
* @param valueNode - GraphQL value AST node to convert.
* @param variables - Optional runtime variable values keyed by variable name.
* @returns JavaScript value represented by the GraphQL value AST.
* @example
* ```ts
* import { parseValue } from 'graphql/language';
* import { valueFromASTUntyped } from 'graphql/utilities';
*
* const value = valueFromASTUntyped(parseValue('[1, 2, 3]'));
*
* value; // => [1, 2, 3]
* valueFromASTUntyped(parseValue('$name'), { name: 'Ada' }); // => 'Ada'
* ```
