Haxe Lang Tiny Essay

created: 23.MAR.2025

I love to learn new programing languages, it help to open the mind to new possibilities and compare different approaches. For instance, I learned Ruby and Scala in 2010, Clojure and Haskell in 2011, Go in 2015, Kotlin 2016, Rust in 2018 and Idris, TypeScript in 2019, 2020 Pandemic strike did a bunch of pocs but not with new langs(crazy year), Zig in 2021, 2022(coding in lots of langs but nothing new) - in 2023 I'm learning Nim and V. Learn at least one lang per year. This post is not complain, it's just to share some toughts, notes and impressions.

Why Haxe

Multi-plataform
Good for Games
High-level strictly-typed
Can build cross-platform applications targeting JS, C++, C#, Java, JVM, Python, Lua, PHP, Flash

My Feelings (12-Jan-2025 haxe 4.3.6)

Cool
Fun
Syntax feels like JavaScript
You will see slighly different outputs depending on the target language

Show me the code

My POCs with Haxe: https://github.com/diegopacheco/haxe-playground

1 - OOP Support

Haxe has classes, constructors and several OOP features like Java.

class Point {
    var x:Int;
    var y:Int;
  
    public function new(x, y) {
      this.x = x;
      this.y = y;
    }
  
    public function toString() {
      return "Point(" + x + "," + y + ")";
    }
}

class Main {
    static public function main() {
        var p = new Point(10, 20);
        trace(p.toString());
    }
}

2 - Generics

Like Java, Scala or Kotlin, Haxe has support for generics.

TODO

@:generic
class MyValue<T> {
  public var value:T;

  public function new(value:T) {
    this.value = value;
  }
}

class Main {
  static public function main() {
    var a = new MyValue<String>("Hello");
    trace(a);

    var b = new MyValue<Int>(42);
    trace(b);
  }
}
