console: console exposing non-implemented methods #12675
Description
In master, console is now exposing non-implemented methods found generally on the browser side but not currently implemented in Node.js:
james@ubuntu:~/node/node$ node -v
v7.9.0
james@ubuntu:~/node/node$ node
> console.
console.__defineGetter__ console.__defineSetter__ console.__lookupGetter__ console.__lookupSetter__ console.__proto__ console.constructor console.hasOwnProperty
console.isPrototypeOf console.propertyIsEnumerable console.toLocaleString console.toString console.valueOf
console.assert console.dir console.error console.info console.log console.time console.timeEnd
console.trace console.warn
console.Console console._stderr console._stdout console._times
> console.
> .exit
james@ubuntu:~/node/node$ ./node -v
v8.0.0-pre
james@ubuntu:~/node/node$ ./node
> console.
console.__defineGetter__ console.__defineSetter__ console.__lookupGetter__ console.__lookupSetter__ console.__proto__ console.constructor console.hasOwnProperty
console.isPrototypeOf console.propertyIsEnumerable console.toLocaleString console.toString console.valueOf
console.assert console.dir console.error console.info console.log console.time console.timeEnd
console.trace console.warn
console.Console console._ignoreErrors console._stderr console._stderrErrorHandler console._stdout console._stdoutErrorHandler console._times
console.clear console.count console.debug console.dirxml console.group console.groupCollapsed console.groupEnd
console.markTimeline console.profile console.profileEnd console.table console.timeStamp console.timeline console.timelineEnd
> console.
For instance, typeof console.group returns function, even tho console.group() is not implemented by Node.js at all currently. Calling these appear to be non-op:
> console.group('test')
undefined
> console.groupEnd()
undefined
>
These appear to originate from V8.
