What information was incorrect, unhelpful, or incomplete?

There are a few errors that can be thrown from the TypedArray constructors, that remain undocumented.

What did you expect to see?

The following are documented, but ideally should be placed an "Exceptions" section to make it obvious:

• Construction throws for BigInt <-> non-BigInt mismatch.
• Construction throws for misaligned byte offset.
• Construction throws for misaligned byte length.

The following are undocumented:

• Construction throws for a detached buffer.
• Construction throws for a byte offset that exceeds the bounds of the buffer.
• Construction throws for a length that exceeds the bounds of the buffer.

Do you have any supporting links, references, or citations?

The specification: https://tc39.es/ecma262/multipage/indexed-collections.html#sec-initializetypedarrayfromarraybuffer.

Do you have anything more you want to share?
