Most of the time, this type of driver controls the data sent from the user interaction interface, such as the keyboard, mouse, and game lever. Static Image architecture (STI) is not a driver at all, but a means of acquiring scanners and static cameras using micro drivers.

Regardless of the type, they are property, and the property value can also be a function, when the property is called method.Custom objects in JavaScript (user-defined local objects) are mutable at any time. The properties of built-in local objects are also mutable. You can create an empty object first, and then add functionality to it when you need it. "Object literal notation (l

JSON means JavaScript object Notation, which is a common format for data representation in JavaScript, and the JSON data format is much like the object in javascript:{"Name": "Value", "some": [1, 2, 3]}The difference is that, relative to the property name in the object, the key name in the JSON must be wrapped in quotation marks. This is only required in special attribute names when the object is famous:{"First name": "Dave"}.To parse a JSON data into a JavaScript object, it is best to use Json.

The array in the parameter is treated as a table column and sorted by rows-similar to the SQL order by clause function. The first array is the main array to be sorted. If the rows (values) in the array are the same, they are sorted according to the corresponding values in the next input array.
