## Notes

-   The function [percent-encodes][percent-encoding] an **entire** `string`. Hence, if provided a URI, the function [percent-encodes][percent-encoding] the entire URI.

    ```javascript
    var out = percentEncode( 'https://en.wikipedia.org/wiki/Mode_(statistics)' );
    // returns 'https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMode_%28statistics%29'
    ```

    To [percent-encode][percent-encoding] a URI, split the URI into separate components, [percent-encode][percent-encoding] relevant components, and then reassemble.
