commitmentsES5 updated the language in 2009, which introduced Object.create (), Object.defineproperty (), Getter and setter methods, s Trict mode and JSON objects. I've used all of these features, and I love ES5 's contribution to language. However, none of these features has a huge impact on the way I write JS code. The most important innovation for me is probably the new array method:. Map,filter and so on. However, ES6 is decidedly different. It is the product of many years of harmonious wor

The last one said we had a preliminary business analysis and got the user, business use case and business scenario model. These three outcomes form the basic requirements framework and delineate the scope of the business. A baseline should be made at this time. Of course, the first baseline contains very thick content, and there is more work to be done to achieve the full requirements. This article is abou

JQuery-1.9.1 source code analysis series (15) animation processing, jquery-1.9.1 source code First, you must have basic knowledge about queues. See the previous chapter. 　　A. Detailed description of the animation entry jQuery. fn. animate function Execution Process Call jQuery. speed according to the parameters to obtain the animation-related parameters and obtain an object similar to the following. Then,

frequent and complex to use, checking for deadlocks is very effective for lock debugging, especially with Thread_levels state information output for debugging, and it is very meaningful to troubleshoot deadlocks.Deadlock:6. SummaryFrom the above analysis you can know that InnoDB in addition to the implementation of the operating system provided by the latch architecture package unexpectedly, but also provides the atomic operation level of the custom

JQuery-1.9.1 source code analysis series (10) Event System-event Commission, jquery-1.9.1 source code JQuery event binding has several outstanding features: 1. You can bind an unlimited number of processing functions. 2. events can be delegated to the ancestor node, and do not have to be bound to the corresponding node. 3. Chain Operation 　　 The following mainly analyzes the event Delegate design. The event

first 6 bytes (Page:4 boffset:2) represent the fil_addr_t information relative to their previous node, and the last 6 bytes represent the fil_addr_t of 1 node relative to themselves. In addition to flst_node_t, the disk list also has a header information flst_base_node_t, the header information is a node number Flst_len (4 bytes) + flst_first (6 bytes) + flst_ Last (6 bytes). 1.1 Structure relationship of a disk-linked list2.space Structural AnalysisIn the InnoDB tablespace, all data is stored

Source code analysis of javaslist in Java Collection series, and javaslist source code In the previous article, we analyzed the underlying implementation of ArrayList and learned that the underlying implementation of ArrayList is based on arrays. Therefore, it has the characteristics of fast search modification and slow insertion and deletion. The sort List introduced in this article is another implementati

have been looking at the donkey code, online in-depth analysis of the article is not much, perhaps this and donkey's code is too large, the code quality is not high may be related. But more may be do not want to share, reluctant to share. In fact, it is the open source of the people do not share the slow to see can understand. Due to the time relationship I will be the
