Haxe中的数组推导使用现有的语法使数组可以更简洁的初始化。它通过 for 或者 while循环构造： > Array comprehension in Haxe uses existing syntax to allow concise initialization of arrays. It is identified by for or while constructs: ~~~ class Main { static public function main() { var a = [for (i in 0...10) i]; trace(a); // [0,1,2,3,4,5,6,7,8,9] var i = 0; var b = [while(i < 10) i++]; trace(b); // [0,1,2,3,4,5,6,7,8,9] } } ~~~ 变量 a 是被初始化为一个数组，保存从0到9的数值。编译器生成的代码，添加每次循环迭代的值到数组中，所以跟下面的代码是等价的： > Variable a is initialized to an array holding the numbers 0 to 9. The compiler generates code which adds the value of each loop iteration to the array, so the following code would be equivalent: ~~~ var a = []; for (i in 0...10) a.push(i); ~~~ 变量 b 是初始化为一个数组，保存同样的值，但是通过一个不同的推导样式，使用了 while 循环而不是 for 。再一次，跟如下的代码是等效的： > Variable b is initialized toan array with the same values, but through a different comprehension style using while instead of for. Again, the following code would be equivalent: ~~~ var i = 0; var a = []; while(i < 10) a.push(i++); ~~~ 循环表达式可以是任何类型，包括条件和嵌套的循环，所以如下的内容会如预期运行： > The loop expression can be anything,including conditions and nested loops,so the following works as expected: ~~~ class Main { static public function main() { var a = [ for (a in 1...11) for(b in 2...4) if (a % b == 0) a+ "/" +b ]; // [2/2,3/3,4/2,6/2,6/3,8/2,9/3,10/2] trace(a); } } ~~~
