These two scripts are both used to detect the input of the user's direction keys. Execute the following to see what is the difference between them. The difference between them is that the former can respond to the input of multiple keys at the same time, such as holding down the up key and the right key at the same time, and the character can move diagonally. However, the latter belongs to the event building block of response class and can only respond to one demand at the same time and can only move in one direction.
The above is just a synchronous chain of responsibilities, We let each node function return a specific value "nextSuccessor" synchronously, To indicate whether to pass the request to the next node, we will often encounter AJAX asynchronous requests in our development. After the request is successful, we need to do something so-and-so. At this time, if we apply the above synchronous request again, it will not take effect. Let's understand and use asynchronous responsibility chain to solve this problem. We add another prototype method Chain.prototype.next to the Chain class to manually pass the request to the next node in the responsibility chain.
Therefore, operators must support their selected frequency bands and some selected roaming bands; Terminal suppliers, on the other hand, tend to provide a small but diversified number of terminal products to increase their sales. This will lead to an increase in the demand for band support. Another result is that the use of frequency bands does not require reliance on Radio Frequency Access Technology (RAT), but the radio must still be able to identify various RATs used and take corresponding actions.
