Revealing Constructor Pattern

Create multiple instances of script with public and private methods.

Example: a plugin.

Change MyPlugin to whatever namespace you’d like to use for your plugin. Constructors start with a capital letter.

Examples

// Instantiate the plugin
var plugin = new MyPlugin();

// Use public methods
plugin.doSomething();
plugin.init();
