Some functions modify the Array, others do not. Why? Is there a way to "filter" those functions?
You're unlikely to see any new methods being added to JavaScript's Array that would modify an array in place like reverse() and sort() do. In fact some of the new methods that are being added are versions of reverse() and sort() (and splice()) that create copies rather than modifying the originals. Read more about them here: Proposal: Change Array by copy.

-
Show HN: Deon.land – Deno.land?
This could be implemented as an import assertion[1]:
import foo from 'http://example.com/foo' assert { sha256sum: '...' }
This feature would even be useful in the web platform in general. Along with an assertion for importing plain text files (not just JSON files).

Updates from the 94th TC39 meeting
Worth noting that Import Assertions were downgraded to stage 2 from stage 3. The proposal page may continue to say "stage 3" until it can be updated.

Import Assertion support on Safari?
I wouldn't use import assertions in any browser since they are still a stage 3 proposal so any browser which implements them is doing before it is standardized and shouldn't be relied upon for anything that matters.
