ES 2021 spec-compliant shim for Promise.any. Invoke its "shim" method to shim `Promise.any` if it is unavailable or noncompliant. **Note**: a global `Promise` must already exist: the [es6-shim](https://github.com/es-shims/es6-shim) is recommended.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment that has `Promise` available globally, and complies with the [spec](https://tc39.es/ecma262/#sec-promise.any).

Most common usage:
```js
var assert = require('assert');
var any = require('promise.any');

var resolved = Promise.resolve(42);
var rejected = Promise.reject(-1);
var alsoRejected = Promise.reject(Infinity);

any([resolved, rejected, alsoRejected]).then(function (result) {
	assert.equal(result, 42);
});

any([rejected, alsoRejected]).catch(function (error) {
	assert.ok(error instanceof AggregateError);
	assert.deepEqual(error.errors, [-1, Infinity]);
});

any.shim(); // will be a no-op if not needed

Promise.any([resolved, rejected, alsoRejected]).then(function (result) {
	assert.equal(result, 42);
});

Promise.any([rejected, alsoRejected]).catch(function (error) {
	assert.ok(error instanceof AggregateError);
	assert.deepEqual(error.errors, [-1, Infinity]);
});
```

## Tests
