Hi,
Can I stream values and operate on them like this ? I have a map and I
would like to stream them. I also want to chain the functions. So, for example,
I may sort the map's values and pass them on.
map.entries((e,m) = sort by using a predicate ).foreach(manipulate the map's
values);
The entries method of a Map doesn't take a function. It does return an array
though. That array contains [key, value] arrays. So you could do this.
map.entries().sort(([k1, v1], [k2, v2]) = k1.localeCompare(k2)).forEach(([k,
v]) = do-something);

That line matches my Java code almost exactly. My traceur transpiler though
throws ‘TypeError: map.entries(...).sort is not a function’. Should I switch
the traspiler ?
Thanks,
Mohan

In the draft ES6 spec, getting or setting array indices on detached
TypedArrays raises a TypeError. However, both V8 and SpiderMonkey seem to
return undefined from reads and silently succeed on writes. These semantics
have probably been shipping for some time.
As an implementer, I'm not sure what
entries() returns an iterator.
To sort you need to convert to an array first.
let a = [...map.entries()];
a.sort()
