* Use `sessionStorage` to remember the previous results of calls to `browserSupportsEmoji()` for 1 week.
* Optimize reading from canvas by supplying the `willReadFrequently` option for the 2D context.
* When `OffscreenCanvas` is available, offload `browserSupportsEmoji()` to a web worker to prevent blocking the main thread. This is of primary benefit to Safari which does not yet support `willReadFrequently`.
* Remove obsolete support for IE11 since promises are now utilized. Nevertheless, ES3 syntax is maintained and IE11 will simply short-circuit.

This allows developers to register scripts with an intended loading strategy by changing the `$in_footer` parameter of `wp_register_script` and `wp_enqueue_script` to an array that accepts both an `in_footer` and `strategy` argument. If present, the loading strategy attribute will be added to the script tag when that script is printed to the page as long as it is not a dependency of any blocking scripts, including any inline scripts attached to the script or any of its dependents.

After [44359] it is impossible to not use ES6 syntax for some logic in the `Gruntfile.js`, so adjust the `esversion` setting for the `Gruntfile.js` to 6. Because the previous setting in `.jshintrc` was not compatible with setting `esversion`, set the `esversion` in the `.jshintrc` explicitly.
See #44492.

JSON files don't need a particular indent style, this was just inherited from the jQuery `.editorconfig`, that we based ours on.
`package.json` is staying in the 2-space-indent group for now, due to npm 3 and 4 having issues. Upgrading to npm 5 will allow us to remove `package.json`, too.
Props netweb.

This .jshintrc is adopted from the jQuery project, with some basic modifications (such as single quotes instead of double quotes). This pretty closely follows our current JS standards and rather closely resembles our PHP standards, especially the love of whitespace. The major changes are enforcing === and always using braces for if statements.
