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. | {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | 712260429 |
