# cached-iterable
2+
3+
`cached-iterable` exposes the `CachedItearble` class which implements the
4+
[iterable protocol][].
5+
6+
You can wrap any iterable in these classes to create a new iterable which
7+
caches the yielded elements. This is useful for iterating over an iterable many
8+
times without depleting it.
9+
10+
[iterable protocol]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#The_iterable_protocol
11+
12+
## Installation
13+
14+
`cached-iterable` can be used both on the client-side and the server-side. You
15+
can install it from the npm registry or use it as a standalone script (as the
16+
`CachedIterable` global).
17+
18+
npm install cached-iterable
19+
20+
## How to use
21+
22+
```js
23+
import assert from "assert";
24+
import {CachedIterable} from "cached-iterable";
25+
26+
function * countdown(i) {
27+
while (i--) {
28+
yield i;
29+
}
30+
}
31+
32+
let numbers = new CachedIterable(countdown(3));
33+
34+
// `numbers` can be iterated over multiple times.
35+
assert.deepEqual([...numbers], [3, 2, 1, 0]);
36+
assert.deepEqual([...numbers], [3, 2, 1, 0]);
37+
```
38+
39+
## Compatibility
40+
41+
For legacy browsers, the `compat` build has been transpiled using Babel's [env
42+
preset][]. It requires the regenerator runtime provided by [babel-polyfill][].
43+
44+
```javascript
45+
import {CachedIterable} from 'cached-iterable/compat';
46+
```
47+
48+
