JavaScript is executed in segments. The definition function statements in a piece of code are executed first, which seems to be a bit like the compilation concept of static language. Therefore, this feature is also called "pre-compilation" of JavaScript ".A function is an object. It only adds a bracket () operator to an object. This operator is used to execute the function logic.Call method exampleFunction WhoAmI () // defines a function WhoAmI{Alert ("I'm" + this. name + "of" + typeof (this ));

Mongodb provides an interesting "Multi-key" feature that automatically indexes the array values of objects. Tags are a good example. Suppose you have an article that contains many classification tags:
$ dbshell> db.articles.save( { name: "Warm Weather", author: "Steve",tags: ['weather', 'hot', 'record', 'april'] } )> db.articles.find(){"name" : "Warm Weather" , "author" : "Steve" ,"tags" : ["weather","hot",
