Question-11. How does Haxe handle type inference?
Answer-11: Haxe can automatically determine the type of a variable based on its value at initialization.
Question-12. What is the @:meta syntax in Haxe?
Answer-12: @:meta represents metadata annotations for customizing the behavior of classes, fields, or methods.
Question-13. What is a typedef in Haxe?
Answer-13: A typedef defines a new type based on a structure, e.g., typedef Point = { x: Int, y: Int };.
Question-14. What is the use of enums in Haxe?
Answer-14: Enums define a set of named values, often for states or options, e.g., enum Direction { Up; Down; }.
Question-15. How do you declare an interface in Haxe?
Answer-15: Use the interface keyword, e.g., interface Animal { function speak():Void; }.
Question-16. What is the purpose of the @:keep metadata in Haxe?
Answer-16: @:keep prevents the Haxe compiler from removing unused code during dead code elimination.
Question-17. How do you use generics in Haxe?
Answer-17: Use angle brackets, e.g., class Box
Question-18. What is a module in Haxe?
Answer-18: A module in Haxe is typically a single .hx file containing classes, functions, or other definitions.
Question-19. How do you import a class or module in Haxe?
Answer-19: Use the import keyword, e.g., import mypackage.MyClass;.
Question-20. What is a package in Haxe?
Answer-20: A package is a way to organize modules into namespaces, usually represented by folder structures.
Question-21. What is the @:native metadata in Haxe?
Answer-21: @:native specifies an external name for a class or method when compiling to certain targets.
Question-22. How do you perform conditional compilation in Haxe?
Answer-22: Use #if, #elseif, and #end, e.g., #if js trace("JavaScript target"); #end.
Question-23. What are abstracts in Haxe?
Answer-23: Abstracts are a way to define custom types with specific behavior while being based on another type.
Question-24. How do you create a class in Haxe?
Answer-24: Use the class keyword, e.g., class MyClass { public var x:Int; public function new() {} }.
Question-25. What is the @:build metadata in Haxe?
Answer-25: @:build is used to generate or modify code during compilation via macros.
Question-26. How do you handle exceptions in Haxe?
Answer-26: Use try, catch, and throw, e.g., try { /* code */ } catch(e:Dynamic) { trace(e); }.
Question-27. What is the Std library in Haxe?
Answer-27: The Std library provides standard utility functions like Std.string() and Std.parseInt().
Question-28. What is the difference between static and dynamic in Haxe?
Answer-28: static methods or fields belong to the class, while dynamic means the type can change at runtime.
Question-29. What is the purpose of the @:generic metadata?
Answer-29: @:generic is used to create a specialized version of a generic class or function.
Question-30. How do you use switch in Haxe?
Answer-30: Use switch to handle multiple cases, e.g., switch(x) { case 1: trace("One"); }.
Question-31. How do you concatenate strings in Haxe?
Answer-31: Use the + operator, e.g., var result = "Hello " + "World";.
Question-32. What is the role of the Main class in Haxe projects?
Answer-32: The Main class serves as the entry point for a Haxe application, typically containing a main method.
Question-33. What is the purpose of the @:enum metadata?
Answer-33: @:enum is used to define a type-safe enum that can work with additional features like reflection.
Question-34. How do you define a static method in Haxe?
Answer-34: Use the static keyword, e.g., static function greet():Void { trace("Hello!"); }.
Question-35. What is the Map type in Haxe?
Answer-35: Map is a collection type that associates keys with values, implemented differently depending on the target.
Question-36. How do you handle asynchronous operations in Haxe?
Answer-36: Use libraries or frameworks like Promise, Future, or Haxe's native async features.
Question-37. What is the difference between @:native and @:extern?
Answer-37: @:native changes the name of a class or method for the target, while @:extern declares external dependencies.
Question-38. How do you create a loop in Haxe?
Answer-38: Use for or while, e.g., for (i in 0...10) trace(i);.
Question-39. What is the Null
Answer-39: Null
Question-40. How do you use the trace function in Haxe?
Answer-40: Use trace for debugging, e.g., trace("Debug Message");.
Question-41. What is the @:final metadata in Haxe?
Answer-41: @:final prevents a class from being extended or a method from being overridden.
Question-42. How do you work with reflection in Haxe?
Answer-42: Use the Reflect API for runtime type information and operations.
Question-43. What are extern classes in Haxe?
Answer-43: extern classes represent external libraries or APIs, allowing Haxe to interact with them.
Question-44. How do you define constants in Haxe?
Answer-44: Use static inline, e.g., static inline var PI:Float = 3.14159;.
Question-45. What is the difference between @:optional and @:dynamic?
Answer-45: @:optional indicates optional fields in abstracts or typedefs, while @:dynamic allows adding fields at runtime.
Question-46. How do you manage dependencies in Haxe?
Answer-46: Use haxelib, Haxe's package manager, to install and manage libraries.
Question-47. How do you use Haxe for game development?
Answer-47: Combine Haxe with frameworks like OpenFL, Heaps, or HaxePunk for game development.
Question-48. What is a @:coreApi in Haxe?
Answer-48: @:coreApi is used to indicate that a class or method is part of Haxe's core API.
Question-49. How do you run Haxe code?
Answer-49: Use the Haxe compiler, e.g., haxe -main Main -js output.js.
Question-50. How do you debug Haxe code?
