conditional symbol to simplify it:Var direction = x If the condition is true, the value following the question mark is used. Otherwise, the value following the colon is used.
Store data in JSON format
Before I found JSON, I used various crazy methods to store data in JavaScript's inherent data types, such as arrays, strings, there are symbols that are easy to split and other annoying things in the middle. After Douglas Crockford invented JSON, everything changed. Using JSON, you can use JavaScr
number of words, we must make a lot of changes and be very careful not to make mistakes. From an object-oriented perspective, this is unscientific.
Put the phrase string list into a text file
Therefore, we can use another way of thinking to construct a program:
Moving all words to a text file outside the Code organizes the file structure according to certain rules, such as a line of name, which is also indirect.
Create a folder (word.txt) and store it in the tmp directory: Joe-Bob "Handyman" Br

For example, I try to find her materials and photos, but I will not try to use them in vain. Because every time I listen to her songs, there is always a picture in my thoughts:On the top of the mountains, the silver moonlight flowing

You can use JSON directly in JavaScript, or even as a format returned by the API, which is applied in many APIs, for example:Copy codeThe Code

You can directly use JSON in JavaScript, or even return data objects as some APIs. The following code calls an API of delicious.com, the famous bookmarkdon.com, and returns all your bookmarks on the website, and displayed on your own website:Copy
', '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: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 the ternary operator. For example:Var direction;If (x Direction = 1;} Else {Direction =-1;}

However, it should also be noted that the actual name/value pairs in the record can differ between the different main entries (programmers,

It's not hard to understand. In this example, there is only one variable named, and the people value is an array of three entries, each of which is a person's record containing the first name, last name, and e-mail address. The preceding example shows how to combine records into a single value in parentheses. Of course, you can use the same syntax to represent multiple values (each value contains multiple records):
