V8 native syntax in Chrome

Question

Nodejs has special flag --allow-natives-syntax. Is it possible to pass such thing to Google Chrome? Or maybe devtools provide some other way to access such information?

// running node with `--allow-natives-syntax` flag

var obj = { a: true, b: false };
console.log(%HasFastProperties(obj)); // true (Fast mode)
delete obj.a;
console.log(%HasFastProperties(obj)); // false (Dictionary mode)

Answer 1

Yes, you can pass that flag to Google Chrome if you start Chrome with --js-flags="--allow-natives-syntax".

(I should point out that you should not generally run Chrome with that flag turned on; use it only for debugging of websites you trust.)
