description: Correctly parses the JSON representation of an array

  # 1.4 ParseJSONModule ( source )

  The abstract operation ParseJSONModule takes a single argument source which
  is a String representing the contents of a module.

  1. Let json be ? Call(%JSON.parse%, undefined, « source »).
  2. Return CreateDefaultExportSyntheticModule(json).

  To more fully verify parsing correctness, the source text of the imported
  module record includes non-printable characters (specifically, all four forms
  of JSON's so-called "whitespace" token) both before and after the "value."
