arguments property of ReferenceError instance?

[vsemozhetbyt]

• Version:
• Platform: Windows 7 x64
• Subsystem: doc, errors

errors.md states:

ReferenceError instances will have an error.arguments property whose value is an array containing a single element: a string representing the variable that was not defined.

However, it seems this property does not exixst anymore in the actual Node.js versions:

try {
  doesNotExist;
} catch (err) {
  console.log(Object.getOwnPropertyNames(err));
}

  // v8 4.5.103.45 (Node.js 4.8.0 x64)

[ 'stack', 'message' ]

  // v8 5.1.281.93 (Node.js 6.10.0 x64)

[ 'stack', 'message' ]

  // v8 5.5.372.40 (Node.js 7.6.0 x64)

[ 'stack', 'message' ]

  // v8 5.6.326.55 (Node.js 8.0.0-nightly20170222a1802e670d x64)

[ 'stack', 'message' ]

  // v8 5.8.202 (Node.js 8.0.0-pre x64)

[ 'stack', 'message' ]

Is this an unintended loss or is this property removed intentionally?

I am guessing error.arguments is just a non-standard property and went away quitely in a V8 update?(the spec doesn't specify such a property).

[vsemozhetbyt]

Should I remove the statement and the code example?

@vsemozhetbyt Good idea.
