12 types of routines that JavaScript implements to inherit

If you are used to understanding and analyzing problems from the perspective of "class", then the inheritance implementation based on constructors is more suitable for you, and the 01~06 method is based on constructors.
If you are only dealing with specific objects or instances, then the object-based inheritance implementation is more appropriate for you, and the 07~12 approach is object-based.

number	prototype chain	example
01	prototype chain (Classic mode)	Child.prototype = new parent ();
02	Inherit only the prototype of the parent constructor	Child. prototype = Parent. prototype;
03	Borrowing constructors	function Child () { parent.apply (thisarguments);}
04	Temporary constructors	function extend(child,parent) { varF = function() {}; F.prototype =Parent. prototype; Child.prototype =NewF (); Child.prototype.constructor = child; Child.uber =Parent. prototype;}
05	Copy the prototype property of the parent constructor	function extend2 (Child, Parent) { var p = Parent.prototype; var C = child.prototype; for (Vari in P) {C[i] = P[i]; } c.uber = P;}
06	Borrowing constructors and copying prototypes	function Child () { parent.apply (thisarguments);} Extend2 (child,parent);
07	object-based shallow copy	function shallowcopy (p) { var c = {}; for (var i in p) {C[i] = P[i]; } c.uber = P; return C;}
08	Deep copy of Object-based	function shallowcopy (p) { var c = {}; for (var i in p) {C[i] = P[i]; } c.uber = P; return C;}
09	Prototype inheritance	function object (o) { function f () {} f.prototype = O; return new F ();}
10	Hybrid mode of prototype inheritance and attribute copy	function objectplus(o, Stuff) { varN function F() {} f.prototype = O; n =NewF (); N.uber = O; for(varIinchStuff) {N[i] = Stuff[i]; }returnn;}
11	Multiple inheritance	function multi() { varn = {},stuff, j =0, Len =arguments. length; for(j =0; J < Len; J + +) {stuff =arguments[j]; for(varIinchStuff) {N[i] = Stuff[i]; } }returnn;}
12	Parasitic inheritance	function parasite (victim) { var that = object (victim); 1; return that;}
