| * Produces a JavaScript value given a GraphQL Value AST. |
| * |
| * Because no GraphQL type is provided, the returned JavaScript value reflects |

| * | 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' |
