(); Console.log (test2.age)//23来 self-prototypingIn Test1, the attribute of age is found in the instance, so it returns without having to go up to the top (chain related), and test2, which is not found in the instance, then looks up to the upper level.Of course, this instance property will only prevent us from accessing the "that attribute" of the prototype, but will not modify the "that attribute" in the prototype, but if we use the delete operator, we can completely delete the attribute in th
In the beginning of a project, what needs to be prepared for the preliminary work, in the outsourcing company, is a kind of development steps? Below, as I understand, say.Project flowchartLook, from left to right, if we are only a development engineer, we only need to be concerned about the role of "Development engineer".Of course, before the development of the project, most of the work needs to be "project manager" and "Product Manager" to complete, for example, analysis, digestion of customer
prototype is a property of functions and of objects that are created by constructor functions.">Advanced JavaScript---Prototyping and prototype inheritanceprototype is a property of functions and of objects that are created by constructor functions.">In JavaScript,prototype is a property of a function and is also a property of an object created by the constructor.the prototype of the function is an object. It is used primarily when functions are used
code.In the JVM specification, there is no mandatory requirement for the method area to implement garbage collection. Many people are accustomed to calling the method area "permanent generation" because the hotspot virtual machine implements the method area as a permanent generation, so that the JVM's garbage collector can manage this part of the area as if it were managed by the heap, eliminating the need to specifically design a garbage collection mechanism for this part. Since JDK7, however,
class hierarchy that is parallel to the product class hierarchy. 4. When an instance of a class can have only one of several different state combinations. building the corresponding number of prototypes and cloning them may be more convenient than manually instantiating the class each time you use the appropriate state.participants 1. Prototype declares a clone of its own interface. 2. Concreteprototype implements the operation of a clone itself. 3. The Client m

initialize, with the syntax of the Object.defineproperties or Object.defineproperty method type. It allows you to set properties such as enumerable, writable, or configurable.If you want to implement prototype mode yourself, instead of using object.create directly. You can use code like the following to achieve the above example:varVehicleprototype = {init:function(Carmodel) { This. model = Carmodel; }, Getmodel:function() {console.log (' vehicle mould is: ' + This. model); }};functionVehicle (
improve the overall image of the product, so that users feel more real specific functions.2. Users can actually feel, you can also get valuable user feedback.3. The development team can know exactly what kind of prototype you want.4. The user is able to know the product's effect function for the first time without having to wait for a lengthy project cycle to make a lot of changes.5. The development team can have a clearer division of labour and be able to understand the process and changes of
, product, technology, market and operation, but the information flow between the departments is equally important.Because perceptions and understanding of a project and its progress can affect the decisions of the various departments.If everyone on the team can see this information in a timely manner, collaboration will be much more efficient.In the ink knife V4.0 product species, we have added "statistics" function.Team insiders can view project progress information at any time to arrange and
dynamic panel for a long day. The ink knife is quick to use, and one day you can easily make a simple application.2. Fast. Not only do you get started fast, you can quickly share and quickly see how your app works on your phone. Feedback is timely and product improvements are fast. With Zhang Yuan one words, is "only fast not broken."3. PM's Gospel. I believe that pm are always suffering from the prototype, especially the novice, with Balsamiq confident, but Fidelity is too low, always recommen

Product designers often have to deal with the prototype, in addition to the usual sitting at the table to draw paper prototypes, in front of the computer screen using Axure or Balsamiq mockups to draw prototypes, have you ever wondered how on the subway to use the time to record their own fragmented ideas? Or in a café, talking to friends and designing prototypes? With the rapid popularity of tablets, the major prototype design software has launched an ipad version, with them, you can really do

function description, an interactive rule, an introduction, and a place to download the package online.
Step Fifth: Customize the component package. The components that will be completed are generated by Axure custom component functionality, generating component packages by category, which can be exported to local or network users, and then stored in the Axure Custom component library for ease of use.

1. A prototype is a property of a function object whose initial value is an empty object, and the prototype prototype object can add methods and properties.2. The constructor object looks for properties and methods when looking for a prototype after finding the constructor.3. If the properties in the constructor and the properties in the prototype are the same, the constructor will have precedence over the prototype.4. Enumeration properties (for-in)(1). Array Enumerationvar a=[1,2,3];for (var i
, this method needs to be implemented, otherwise an exception will be thrown. In iOS, this method keeps the new copy object and returns it. The caller of this method is responsible for releasing the returned object.In most cases, the implementation of a deep copy does not look complicated. The idea is to copy the necessary member variables and resources, pass them to a new instance of the class, return the new instance, and return to the new instance. The trick is to make sure that the resources
