I was going to suggest a Set, now that ECMA has them…
http://www.ecma-international.org/ecma-262/6.0/index.html#sec-set-objects
```js
if ((new Set([1,2,3,5]).has(a)) {
// stuff
}
```

it could be used like this:
if ( a == 1
();
finally cleanUp();
in the same spirit as
if (foo) doFoo();
else doBar();

Silent catch-alls like that are almost always bad code. I think the

+1 on clear() as it's pithy, understandable, and behaves the same in
Java and Python.
What real benefit comes from drawing this connection between delete()
and deleteAll()? I suspect the everyday programmer won't care, and the
ones who do will look it up.

requires two constructions, one of which is
essentially a waste. If allowing both forms of the constructor is
distasteful, then why not just go with the multiple parameters,
approach, and implement toSet() as a method on appropriate Iterables?

Sorry for the resend. Meant to include the list.
I like this idea a lot! However, what would be the correct behavior of
a method like 'every' on an infinite generator?

What do you think?

I think step should be 0, and step towards end:
Array.range({start: 5, end: 0
the starting index?
String.prototype.until = function (start, needle) {
return + (this.substr(start, this.indexOf(needle)) || this);
}
(The [ +] part is probably not necessary, but it makes it easier to
see the implementation work in the console.)

sense…
Is the difference in overhead between instantiating a new array and
using Array.prototype.slice.call on arguments really worth sacrificing
consistency with the proposed string.prototype.repeat and the very
clean syntax of someArray.repeat(n)?
