How did 11 lines of code cause a breach of tech giants like Facebook, PayPal, and GoDaddy? Do you really need to use jsarray which was introduced natively in JS in 2009, but still has >400 million downloads/month. Trivial packages don't have a trivial impact so should be avoided

Aw, Snap! @FlutterDev Checking if a list is empty crashes Flutter Web. Flutter 3.19.6 Any ideas on how to avoid this? The obvious issue I see in debug “Threads and Variables” is that I have a JSArray instead of a dart List. I think it is related to this.

[324482838][maglev] Fix sandbox violation when allocating an empty array. Initial JSArray map shouldn't have any in-object properties. https://t.co/8tTYciJp9K Added check to verify that this was not mutated by an attacker: SBXCHECK_EQ(map.GetInObjectProperties(), 0);

What I missing on graphbuilding is v0 type checking. If receiver is not a JSArray, it will result in a the fatal error. This generates wrong machine code at release build and crashes on debug build. e.g., code like
I finally find what I missing on building the maglev graph building for ArrayPrototypeSlice
