JS编程建议——21：推荐提高循环性能的策略（2）

建议21：推荐提高循环性能的策略（2）在每个循环中，每次运行循环体都要发生如下操作：第1步，在控制条件中读一次属性（items.length）。第2步，在控制条件中执行一次比较（i < items.length）。第3步，比较操作，观察条件控制体的运算结果是不是true（i < items.length == true）。第4步，一次自加操作（i++）。第5步，一次数组查找（item....

建议21：推荐提高循环性能的策略（1）每次运行循环体时都会产生性能开销，增加总的运行时间，即使是循环体中最快的代码，累计迭代上千次，也将带来不小的负担。因此，减少循环的迭代次数可获得显著的性能提升。例如： var iterations = Math.floor(items.length / 8), startAt = items.length % 8, i = 0; do { switch(s.....
