One,
The way this type of student that person, write like this though inherited, but the parent class is to inherit property in the prototype student
In order to change the type of student he would need to add a "student.constructor = student"
Since this method to inherit the prototype, so if we can only pass parameters when they could pass new parameters, namely student.prototype = new person (and there may write)
You object name = new student (and there can not write parameters)
Therefore, this method has many limitations, so we rarely use
two,
person.call: Borrowing Constructor
This method can be mass participation, but this kind of method can not be inherited
three,
This method is invoked who is who
function:
The following slow implementation, to parse twice
Function is the object
Function declaration:
The second call fun () prints out undefined, because he is the assignment will increase
This looks all right
this：
apply：
apply this first parameter is the object pointed to
The second is an array
The first call and apply, as his second pass is a direct reference
When calling the first item in the array parameter in the first position, followed by recursive
Compare Max:
Delite obj.0 can not be written because the variable name can not start with a number
Use object masquerading quick removal
Note that we define a pseudo-array
Function as a parameter:
You can adjust the sort order sort
Return value as a function of:
Closure:
