structured data in a format that allows JavaScript to navigate easily without XML processing expenses. Fortunately, there is a format that does exist.JavaScript Object AnnotationsIn fact, most of the JavaScript objects are composed of union arrays, numeric indexed arrays, strings, numbers, or nested sets of these types. Because all types can be declared directly with JavaScript, you can statically define the object graph in a single statement. Listing 7 declares an object using JSON syntax and
In a UNIX system, each system and end user task is included in a process. The system always creates new processes, and the process terminates when the task ends or occurs unexpectedly. In this article, you will learn how to control processes and use commands to view your system.
I was fascinated by a single band at a recent street recreation. Indeed, it made me very happy and impressed me. The sole member of this single band used his mouth, thighs, knees and feet to control the harmonica, the b

the work, not after the code has started. Test plans are critical-do you define the right environment, team, resources, and methods to deliver value? This is a problem, but often it is not answered before coding. The existence of this wonderful new test system has caused the problem, and everyone has answered it before heading to the next step.
The completion of the test plan can be defined by the use of test design technology to predefined acceptance criteria. You might shout: "What??" The te
Before we compare the throughput of Muduo and Libevent2, we get the conclusion that Muduo is 18% faster than Libevent2. Some people will say that Libevent2 is not designed for the high throughput of the application scenario, such a more unfair, not win. For the sake of fairness, this time we use Libevent2 's own performance test program (drumming) to compare the Muduo and Libevent2 IO event processing efficiency in high concurrency situations.
Test object
Libevent 2.0.6-RC, source code package
follows:
Var moviesThatNeedBetterWriters = ['Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4'];
For arrays, there is also a special thing like associating arrays. You will find that many codes define objects as follows:
The Code is as follows:
Var car = new Array ();Car ['color'] = 'red ';Car ['wheels'] = 4;Car ['hubcaps'] = 'spinning ';Car ['age'] = 4;
This is crazy. Don't be confused. "Join array" is just an alias of an object.
Another way to simplify the code is to use th
": "Chad Smith","Role": "Drums,percussion"},{"Name": "John Frusciante","Role": "Lead Guitar"}],"Year": "2009"}You can also use JS to store data, the code is as follows:You can even add the stored data generated by the above JS as the return value of the APIThird, use JavaScript native functions as much as possibleFor example, get the maximum value in a set of datavar maxData = Math.max (0,20,50,10);alert (maxData); The maximum value returned is 50For
as the data format
The great Douglas Crockford invented the JSON data format to store data. You can use the native javascript method to store complex data without any extra conversion. For example:
The Code is as follows:
Var band = {"Name": "The Red Hot Chili Peppers ","Members ":[{"Name": "Anthony Kiedis ","Role": "lead vocals"},{"Name": "Michael 'flea' Balzary ","Role": "bass guitar, trumpet, backing vocals"},{"Name": "Chad Smith ","Role": "drums

Val ()); This is not a good use, or the following is introduced, the first has been tested.The people's brains were kicked by the donkey until Java script1.8.1 supported the Trim function (and trimleft,trimright), but now only firefox3.5 support. Because it is too often used to remove whitespace on both sides of a string,
Smith", "role":"drums,percussion" }, { "name":"John Frusciante", "role":"Lead Guitar" } ], "year":"" }
You can directly use JSON in JavaScript, encapsulate it in a function, or even use it as the return value form of an API. We call this JSON-P, and many APIs use this form. You can call a data provider source to directly return JSON-P data in script code:
