Ask the right questions to secure the right Haxe talent among an increasingly shrinking pool of talent.
Haxe is a high-level, cross-platform programming language first introduced in 2005 by its inventor, Nicolas Cannasse. It was developed with the aim to serve as a single language for all platforms, allowing developers to write code once and compile it anywhere (source: Haxe Foundation). The Haxe compiler can output applications targeting JavaScript, Flash Player, Neko VM among others. Its versatility has led it to be utilized in various industries including video game development and web application building (source: GitHub). As of today's digital landscape, Haxe continues evolving while maintaining its core principle of universal applicability.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
Abstracts are a type in Haxe that allows you to create a new type based on an existing one, with its own methods and properties. You would use the 'abstract' keyword to declare an abstract.
You would use the 'class' keyword followed by the name of the class. For example, 'class MyClass { }'. You can then add methods and properties to the class.
In Haxe, '==' is used for equality comparison and '===' is used for identity comparison. '==' checks if the values of two operands are equal or not. '===' checks if two operands refer to the same object or not.
Haxe is a high-level, cross-platform language. It can be compiled to multiple target languages like JavaScript, Python, PHP, C++, and more. This provides a lot of flexibility and reusability of code.
You would use the Haxe compiler with the -js flag, followed by the output filename. For example, 'haxe -js output.js MyProgram'.
Software development is often a team effort. Therefore, good communication skills and the ability to work in a team are crucial for the candidate to interact effectively with other team members.
These are fundamental concepts in programming. A good understanding of these concepts shows the candidate's ability to write efficient, clean, and maintainable code.
Familiarity with different Haxe frameworks like OpenFL, Kha, HaxeFlixel, etc., will allow the candidate to jump into projects quickly and start contributing.
Since Haxe is a multi-platform language, experience in cross-platform development is a great advantage. It shows that the candidate can adapt to different environments and platforms.
Problem-solving is a critical skill for developers as they will often need to troubleshoot issues in code and find efficient solutions.
This is essential as it is the primary skill required for the job. The candidate should be able to discuss the syntax, concepts and functionalities of Haxe in depth.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
You would use the 'extends' keyword. For example, if you have a class 'Animal' and you want to create a 'Dog' class that inherits from 'Animal', you would write 'class Dog extends Animal'.
An interface is a contract for a class, it defines a set of methods that a class must implement. A class in Haxe is a blueprint for creating objects, it can implement one or more interfaces.
Macros in Haxe are a way to generate code at compile time. You would use the 'macro' keyword to define a macro. Macros can be used for tasks like code generation, compile-time calculations, and conditional compilation.
You would use the 'try/catch' statement. The 'try' block contains the code that might throw an exception, and the 'catch' block contains the code that will be executed if an exception is thrown.
A static method belongs to the class itself and can be called without creating an instance of the class. An instance method belongs to an instance of the class and can only be called on an instance of the class.
A skilled Haxe engineer should exhibit a strong understanding of the Haxe language, proficiency in cross-platform development, and problem-solving abilities. Red flags would include lack of knowledge about Haxe's syntax or limitations, inability to discuss past projects in detail, or poor communication skills.
var str:String = 'Hello, World!';
trace(str);
var a:Int = 10;
var b:Int = 20;
trace(a + b);
var arr:Array = [1, 2, 3, 4, 5];
arr.pop();
trace(arr);
import haxe.Constraints.Function;
var f:Function = function() {
trace('Hello, World!');
};
new Thread(f);
class Point {
var x:Int;
var y:Int;
public function new(x:Int, y:Int) {
this.x = x;
this.y = y;
}
}
var p:Point = new Point(10, 20);
class Test {
public static function main() {
var a:Int = 10;
var b:Int = a++ + ++a;
trace(b);
}
}
The final few interview questions for a Haxe candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
There are several ways to optimize the performance of a Haxe program. Some of them include using appropriate data structures, minimizing memory usage, avoiding unnecessary calculations, and using the Haxe profiler to identify and optimize bottlenecks.
Haxe supports several types of collections including Array, List, Map, and Set. You would use an Array when you need a resizable collection, a List when you need a collection with efficient add/remove operations, a Map when you need to associate values with keys, and a Set when you need a collection of unique elements.
You would use the 'class' keyword followed by the class name and then the type parameter in angle brackets. For example, 'class MyGenericClass<T> { }'. You can then use this class with any type.
Public access modifier allows a class, method, or property to be accessed from anywhere. Private access modifier restricts the access to within the class itself.
Haxe supports several types of loops including 'for', 'while', and 'do-while'. You would use a 'for' loop when you know how many times you want to loop, a 'while' loop when you want to loop until a condition is false, and a 'do-while' loop when you want to loop at least once and then until a condition is false.
