JS prototype question What is the relationship between object and function?

var F  functionfunctionfunction() {};

F can access both A and (object and function also, but all instances can only access a); F is an instance of object and function two, so what is the relationship between object and function?

The following is an understanding of object and Function

FinstanceofObjecttrueFinstanceofFunctiontrueObjectinstanceofFunctiontrueFunctioninstanceofObjecttrueObject:functionObject () {[native code]};object.construtorfunctionFunction () {[native code]}; Function:functionFunction () {[native code]}; Function.constructor= = Function;//trueObject= = Function; //false

Can know

1.Object and function have the same constructor functions function function () {[native code]}

2.Object and Function are not equal

instanceof Number     falseinstanceof Function     trueinstanceof Object     Truefunctioninstanceof object     True instanceof Function  true     

3. Other basic types or non-basic types are also instances of the object as well as instances of the function.

If so:

var foo = {};     function  = "Value.a"= "value.b"; Console.log (FOO.A);        // value.aConsole.log (FOO.B);      // undefinedconsole.log (F.A);        // value.aConsole.log (f.b);        // value.b

So:

FOO.A search Path: Foo itself: no--->foo.__proto__ (object.prototype): Value.a found

FOO.B search Path: Foo itself: no--->foo.__proto__ (object.prototype): No--->foo.__proto__.__proto__ (object.prototype.__ PROTO__): No

F.A Find path: F self: no--->f.__proto__ (function.prototype): No--->f.__proto__.__proto__ (object.prototype): Find Value.a

f.b Find path: F self: no--->f.__proto__ (function.prototype): Value.b found

4. The constructor property of the instance object points to its constructor. So object.contructor = = = function, Function.contructor = = function
