[AskJS] Is JavaScript missing some built-in methods?
Stage 3 Change array by copy proposal offers methods like sortTo() that return a new array instead of mutating the original.

Sorry for the bad quality, can someone please explain how this code arranges the numbers in the array from smallest to biggest ? what does a-b do ?
Note: there's a stage 3 proposal that introduces copy = arr.toSorted().

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.

Future Javascript: New Array Methods Coming soon
Since cloning is so common, a new specification has been written which has reached stage 3, which will give us a host of new ways to copy and then change an array. This proposal is called the "Change Array by Copy" proposal. Let's take a look at how it works.
