            Bug ID: 198574
           Summary: JSON.parse throws incorrect exception when called w/o
                    arguments
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Minor
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: shvaikalesh at gmail.com

Test case:
  JSON.parse()

Expected:
  SyntaxError: JSON Parse error: Unexpected identifier "undefined"

Actual:
  Error: JSON.parse requires at least one parameter

ECMA-262: https://tc39.github.io/ecma262/#sec-json.parse
No matter how many arguments are passed, `JSON.parse` always coerces first arg to string (step 1) and attempts to parse it (step 2).
Other browsers throw SyntaxError.
