Pluggy does dependency injection by introspecting the named arguments to the Python function, which I really like.

That's tricker in JavaScript. It looks like the only way to introspect a function is to look at the .toString() representation of it and parse the (parameter, list) using a regular expression.

Even more challenging: JavaScript developers love minifying their code, and minification can shorten the function parameter names.

From https://code-maven.com/dependency-injection-in-angularjs it looks like Angular.js does dependency injection and solves this by letting you optionally provide a separate list of the arguments your function uses:

javascript angular.module('DemoApp', []) .controller('DemoController', ['$scope', '$log', function($scope, $log) { $scope.message = "Hello World"; $log.debug('logging hello'); }]);

I can copy that approach: I'll introspect by default, but provide a documented mechanism for explicitly listing your parameter names so that if you know your plugin code will be minified you can use that instead.
