description: Correctly parses the JSON representation of an array
info: |
# 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."
flags: [module]
features: [import-assertions, json-modules]
