Preface
I recently read the book C #3.0 Core Technology in the library. I think it is quite good to read it. C #3.0 technology covers from basic syntax to new features, it is a good book to learn C #3.0. I wanted to download the electronic version from the Internet but couldn't find it, but I read the English version of C #3.0 in a Nutshell, 3rd Edition, also very good. I plan to take the time to learn some

circumstances to 8 screen around to display. This makes it difficult to read a program or modify a program. It is therefore advisable to extract the block that completes the comparison of independent functions as a single function. A block that accomplishes the same or similar function is extracted independently of a sub-function. It can be found that the simpler the upper-level function is, the more specific work is done by invoking a few sub-functions, the more the underlying function complet

can be a variable, or even an expression. The switch statement uses the strict equality operator when comparing values, so type conversions do not occur.
Any function can implement the return value at any time by the return statement followed by the value to be returned, and any code after the return statement will never be executed.
Strict mode has some limitations on functions:
The function cannot be named eval or arguments;The parameter cannot be named eval or arguments;Two name

The difference is that encodeURI () does not encode special characters that are themselves URIs, such as colons, forward slashes, question marks, and well sizes, while encodeuricomponent () encodes any non-standard characters it discovers.

Core: ECMAScript
Document Object Model: DOM
Browser Object Model: BOM
Core: ECMAScriptHe has nothing to do with the browser, just the syntax, the type, the keywords or something.Document Object Model: DOMDom is to think of HTML as a tree structure so that you can manipulate them through the API.Html:html> head> t
the location of the label If the page requires a lot of JavaScript code, this will undoubtedly cause the browser to have a noticeable delay in rendering the page, while the browser window in the delay period will be blank. To avoid this problem, modern WEB applications typically place all JavaScript references behind the page content in the DOCTYPE HTML>HTML>Head>title>Example HTML Pagetitle>Head>Body>here to put the content -Scripttype= "Text/javascript"src= "Example1.js">Script>Scripttype= "
due to the time and space required for the copy-on-write operation. Second, your program does not need collection to have the most up-to-date information, iterator only with collection information at the time of creation.
consider using multiple collection.Although some collection have minimal synchronization, these synchronization processes are problematic when there are multiple threads involved. Consider using

value (or pointer), the reference point to the object is not involved in replication, That means the last two reference variables point to the same object5. Each execution environment has a variable object associated with it, and all variables and functions defined in the environment are stored in the object. There are many kinds of execution environment, such as global environment, function environment, with environment, and so on, the variable objects of these environments form the scope chai
