One of the best features of knockout is its scalability. Knockout has a large number of extension points that contain a large number of tools to create our applications. Many developers create great sites in addition to knockout core libraries without using any other scripting libraries (even jQuery).
Subscribables
When creating our inventory management program, it is easy to see that observable is a core object in knockout. At the bottom of Observable,observablearray and computed observables
one master's slaves, even if slave has been out of the Organization for a long time. This is useful because the Sentinel cluster must have the ability to reconfigure a recovery-usable slave.
Also, after failover, the failed master will be marked as a slave of the new master, so that when it becomes available, the data will be copied from new master.
Then, sometimes you want to permanently delete a Slave (possibly it used to be a master), you just send a sentinel RESET Master command to all the
enterprise unified implementation of some mandatory configuration will become more convenient.
A framework based on policy management
The PBM framework consists of three parts:
Policy Management: Administrators make a variety of policies.
Explicit management: An administrator checks the compliance of a target against a policy by applying a policy to a specified target or target group, or, more strictly, prohibits the violation of policies on those targets.
Execution mode: PBM in SQL Server

After the AutoComplete obtains the focus, you can find the list of content that matches the entered content in the subscribed data source for the user to choose. This can be used as a previously entered content or as an automatic filling of relevant content, for example, automatically filling the zip code according to the city name... SyntaxHighlighter. all ();
After the AutoComplete obtains the focus, you can find the list of content that matches the

In that case, when OnError is called, the retry logic you have defined will be able to handle it.Here's an example of where we should subscribe to source, for example, to request a throwable only if it is ioexception, otherwise it is not (re-subscribed).Source.retrywhen (New FUNC1Observable extends Throwable>, Observable >>() {@Override public Observable > Call (Observable extends Throwable> errors) { return e
Pure computed observables purely computed monitoring propertiesThe Pure Computational monitoring attribute is introduced in knockout3.2.0, which provides a better choice of speed and memory performance for conventional computational monitoring properties in most cases. This is because the purely computed monitoring property does not need to maintain its dependency if it is not subscribed to itself.It's features: prevents memore leaks prevents memor

The purpose of mounting is to trigger all mounted Methods One by one when this event is triggered to complete the Event Callback mechanism.It can be visually interpreted as n people's subscriptions. The mounting action is to subscribe to a newspaper. In the future, whenever the newspaper is distributed, all subscribers will receive it.The so-called subscriber, observer, and listener are similar descriptions, that is, after an event is trigger
