TypeScript小知识：遍历enum (暂时记录)

enum BlockPrefab{

    BLOCK2 = 0,

    BLOCK4,

    BLOCK8,

    BLOCK16,

    BLOCK32,

    BLOCK64,

    BLOCK128,

    BLOCK256,

    BLOCK512,

    BLOCK1024,

    BLOCK2048

}

let num = BlockPrefab.BLOCK128;

let smth = BlockPrefab[num];

let xx = BlockPrefab[smth];

 ts 的enum编译为js如图所示

BlockPrefab["BLOCK2"] = 0 可以相互转化 以此来实现enum
