在相对短的时间内，把注意力从一个任务切换到另一个任务，这就是“切换上下文”的定义。

这个条件如第35行所示，其中，如果在一段连续的时间内对该列排序，并且以前的排序方向为升序，那么它必须切换为降序排序。
This condition is shown in line 35, where if the column is being sorted for a consecutive time and the previous direction was upward, it must be switched to downward sorting.
因此，在使用模块的情况下，最终用户节省了启动时间，但是当他从一个模块切换到另一个模块时却需要花更多时间，因为每个模块都需要以JIT形式加载。
So in this case of Modules, the end-user saved on startup time, but will end up paying for it when they move from one Module to the next since each new Module will need to be loaded in a JIT manner.
