Hello,
I run following code in ch 1.11.19(debug)，and it will crash by an assertion.

let b = [1.1, 2.2, 3.3];
b[4294967294] = 3;
Array.prototype.copyWithin.call(b, 0, 1);

Crash output:

ASSERTION 7690: (/.../ChakraCore-1.11.19/lib/Runtime/Library/JavascriptArray.cpp, line 9309) direction == -1 || (fromVal + count < MaxArrayLength && toVal + count < MaxArrayLength)
 Failure: (d

Hi,

Following code results in parse error;

let a = 5; //  00000000000000000000000000000101

a >>>= 2;  //  00000000000000000000000000000001
console.log(a);
// expected output: 1

let b = -5; // -00000000000000000000000000000101

b >>>= 2;   //  00111111111111111111111111111110
console.log(b);
// expected output: 1073741822

thanks

spidermonkey/get-latest-version.js currently only supports Beta builds, but it should also be possible to download Nightly builds:

Nightly binaries are available at https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/.
The build-id can either be retrieved by scraping <htt

Would be nice to have a more comprehensive examples/ collection, including logging etc.
