This article mainly introduces prototype in JavaScript. This article describes three methods for accessing prototype objects and how to determine whether there is a prototype link between two objects, if you need a prototype chain, you can refer to the inheritance in JavaScript through prototype chain: each object has another object as its prototype, the object inherits the property from this prototype ). For each object, you can use the following three methods to access its prototype object:
type has only one integer. It can be expressed as-0 or + 0 ("0" is a abbreviation of + 0 ). In practice, this has almost no impact. For example, + 0 =-0 is true. However, you may need to note that when dividing by 0:
42/+ 0; // Infinity42/-0; //-Infinity
If the parameter cannot be converted to a number, NaN is returned.
In non-constructor context (for example, no new operator), Number can be used to perform type conversion.
IsNAN type determination
Number.isNaN(NaN); // trueNumber.isNaN(Numbe

IOS ProtocolBuffer setup and demo, iosprotocolbuffer
This time I set up the ProtocolBuffer compiler for iOS and encountered many problems when compiling *. proto Source files into *. pbobjc. h and *. pbobjc. m files!
There was no problem when building the pb compiler. After compiling the *. proto file, I used cocoaPods to integrate ProtocolBuffers into my project,
During cocoaPods integration, I tried two l

Port forwarding can forward traffic to the specified port of the specified address when the specified address accesses the specified port. If no ip address is specified for the purpose of forwarding, the local host is used by
I. Traditional Prototype-based approach
To be exact, the "class" of distinct Cr into pt cannot be regarded as a real class in a strict sense. There is a relationship between the declared object and the class (estimated:
Instance. _ proto __= InstanceClass. prototype (not supported by ie)
The preceding description: The instance property (_ proto _) is equal to the prototpye of the class. We can see that, the

Binary communication is usually used between various projects, which requires a small bandwidth and fast processing speed ~
Thanks to Trustin Lee, the author of netty, for letting netty naturally support protocol buffer.
This example uses netty4 + protobuf-2.5.0, run in win7, and assuming jdk and maven have been installed.

Protobuf (quickStart), protobufquickstart1. Introduction
Protocol Buffers is a data description language developed by Google. It serializes data and can be used in data storage and communication protocols.
It can be understood as faster, simpler, and smaller JSON or XML. The difference is that Protocol Buffers is in binary format, while JSON and XML are in text format.
Compared with XML, Protocol Buffers has the following advantages:
1. Concise
2. small size, the message size is only 1/10 to 1/3
) collection of properties that can contain simple data types, objects, functions, and functions that are stored in an object property are also called methods of this object. (from the ECMA-262 4.3.3) (Note: The attributes described here are those that can be created and accessed in a JS script (which we call the dominant attribute), excluding the internal attributes that the system automatically assigns to the object.
So why is that simple data type not an object, mainly because the methods in
