Examples for Iterator.prototype.sliding

[slowcheetah]

Can you show an example of the result that should be obtained, based on the specification from this pull request?
For example, what would be the result for the following lines:

const digits = () => [1, 2, 3, 4].values();
const slidingOf2 = Array.from(digits.sliding(2));

I'm concerned that, according to the specification (if I understand it correctly), in the example above we will now get an extra element:

[[1, 2], [2, 3], [3, 4], [4]]

You're mistaken about the behaviour of sliding. I've pushed up a polyfill with tests. Please see c5fe884#diff-e06526b3af9424c409ce1b604f6555f4393bb8f8ff3efa298a8300d0537a0499R103-R105.

@michaelficarra your polyfill is inconsistent with the spec text. Take a look at the place where the first element is removed from the buffer.

Huh, that means #15 was wrong and nobody caught it. Okay, I've pushed ca13b07 which should fix that and make the sliding algorithm steps mirror chunks/windows more closely. PTAL
