(我的第一次尝试是返回此:[1、2、3,[4、5、6,[7、8、9]]],然后我决定使用null分隔符进行操作。) function split(array, cols) { if (cols==1) return array; var size = Math.ceil(array.length / cols); return array.slice(0, size).concat([null]).concat(split(array.slice(size), cols-...
调试可以看到,在执行完callback后,map->descriptor_array->enum_cache已经被修改,其中enum_cache.keys/indices数组的大小都为 1(这里存在指针压缩,所以要右移一位),但是这里栈中保存的enum_length却还是 2。 这里是真不知道map上的enum ...
