Imagine that we are writing a User
class in JavaScript:
function User() { var name; var age; } User.prototype.outputInfo = function() { var el = document.createElement("div"); el.innerHTML = this.name+"("+ this.age+")"; document.body.appendChild(el); }
Now, if we want to use this class from our haXe application, then we have to write the corresponding extern
class as follows:
extern class User { public var name:String; public var age:Int; public function outputInfo():Void; public function new():Void; }
There are several things that you should note:
We have written an extern class, explaining to the compiler that the User
class exists outside our code and can be used from it.
