i kinda want a new DataView(ArrayBufferView) shortcut for new DataView(view.buffer, view.byteOffset, view.byteLength)

We have ArrayBufferView in the language?

hello! I'm new to the tc39 proposal system, but I just wanted to ask if anyone would find a syntax feature like this useful:
instead of using foo = foo.bar, just using foo = .bar or foo .= bar. this just came to my mind since I use things like array = array.map and array = array.filter a lot.

is foo = foo.bar common enough to add syntax for it?

<Jack Works>
in my daily programming I barely write that (maybe because I'm using TypeScript and mostly it doesn't pass the type check)

do any engines optimize queue-like array usage?

This post seems to suggest they do/did: https://esdiscuss.org/topic/queue-feature-request#content-3

“In WebKit the array implementation switches to an amortized constant time deque if you use push/pop/shift/unshift in anger.”
