, when parsing a function declaration, the type (function) is resolved at the same time, but will not execute, parsing the variable declaration, only the variable is resolved, not initialized.
There are also some examples to illustrate (recall), but there is no example of a declaration with the same name, here is a supplementary:
Copy Code code as follows:
Console.info (typeof fn);//function, declaring elevation, taking function as the standard
var fn = ';
function fn () {
I. Overview:
In actual work, it is estimated that two ISP lines, such as China Telecom and China Netcom, are often connected using ASA, and there is not enough budget to buy load balancing equipment, however, we want to achieve load sharing and automatic switching of links. We want to return traffic from China Telecom, from China Telecom to China Telecom, and from China Netcom to China Telecom. When one of
the node. When the user's request arrives at the specified node, the CDN server (the cache on the node) is responsible for providing the user with the content requested by the users. The specific process is: users in their own browser to enter the site to visit the domain name, browser to the local DNS request resolution of the domain name, local DNS will send requests to the site's primary DNS, the primary DNS based on a series of policies to determine the most appropriate CDN node at that tim
The theft of ADSL accounts allows others to use their own accounts to access the Internet at will and to consume data online at will, according to the authoritative data of China Netcom and China Telecom, 90% of the incoming calls on the consulting phone call reflect the theft of the ADSL account. Therefore, Beijing nethe and China Telecom released the latest notice on binding ADSL accounts and telephones in September 4, hoping to reduce the number of
Thousands of web site trap Server to maintain the dilemma
A server-hosting company suddenly evaporated in April this year, leaving thousands of of its sites in the company without a "landlord" overnight.
The company rented the computer room of Netcom, due to more than 2 million yuan in arrears to the Netcom company costs, after the incident, the company's hosting in the company's thousands of servers for
China North and South Telecom split their families earlier. I personally think it is the biggest failure of the Ministry of Information Industry. Now, China Netcom is also to be demolished, which are classified as mobile and New China Unicom, leading to bottlenecks in informatization, this is the problem of North-South communication. If the data center is located in the data center of North China Netcom, ac
Let you achieve: access to the telecommunications server to automatically use telecommunications lines, and access to the Netcom server automatically use the Netcom line. Internet friends are basically clear, the North Netcom and southern Telecom Internet communication bottlenecks, and not to say what is the cause of the specific, but this does give the applicati
It is very useful to know about two-line policy routing. Here we mainly explain three implementation methods of Two-line policy routing, I have referred to the post on Dual-line policy routing of China Telecom + China Netcom in the next Forum, and summarized several ways to achieve dual-Line Policy Routing Based on the actual environment as follows, hoping to help anyone who needs it, the dual-line routing is much more complicated than the single-line

I have only recently started to study webrtc deeply. If I have any questions, please leave a message.How to generate WEBRTC vs engineering under Windows see my last article.But when I modify the project, such as adding cc and H files, adding a third-party dependency library, you will find that the VS modification is useless. VS can only be used when a code reader and editor are available.This time we need to understand the principle of WEBRTC construction Engineering:1, WEBRTC through

Introduction : in the discussion of this issue, among the group of Friends of the old lone comrade also provides a lot of very valuable information, so we re-organize the data again, from the comparison of the underlying technical principles of a re-analysis.

Original address: http://www.cnblogs.com/xitang/p/3575255.htmlBelieve that a lot of friends will be some of these nouns around some of the head, many friends think that smart DNS with two-line acceleration, CDN acceleration is similar technology. In fact, although their purpose is one: to allow users to access the site faster. But the principles of their application are vastly different.It must be clear to everyone that these are more common ways to host acceleration. So the text mainly introduc
With the development of the routing industry, its market competition is very fierce. For users, how to set the correct route, is also a very important issue, here I studied some network router settings, here to take out and share with you, hope for everyone useful. As we all know, China Netcom and China Telecom are the two monopoly of domestic network access service providers. There are some problems in line and site visits, that is, if your network b
