'stream' values

[Mohan.Radhakrishnan at cognizant.com]

That was helpful.

I find it interesting that ES6 code is very similar to Java 8 lambdas.

Thanks,
Mohan

entries() returns an iterator.

To sort you need to convert to an array first.

let a = [...map.entries()];
a.sort()

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 ?

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);

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);

Thanks,
Mohan
