Javascript - Objects, inheritance, classes

Описание: Objects, inheritance, classes

00:00:00 Prototypal Inheritance – [[Prototype]], __proto__, Object.getPrototypeOf()/setPrototypeOf(), prototype chain lookup, write/delete act on object directly
00:03:25 F.prototype & Constructor Property – setting [[Prototype]] via new, default prototype with constructor, replacing prototypes
00:05:41 Native Prototypes – built-in constructor prototypes, inheritance tree, modifying native prototypes, primitive wrapper objects
00:08:27 Classes – class keyword, constructor(), class methods, strict mode, classes as functions under the hood, methods stored in prototype, [[FunctionKind]], not just syntactic sugar
00:11:00 Class Expressions – defining classes inside expressions, returning classes from functions
00:11:47 Getters/Setters in Classes – get/set keywords, computed property names
00:13:12 Class Properties – instance properties in constructor, public field declarations (2020+)
00:13:58 Static Class Members – static methods, properties, and initialization blocks
00:14:17 Private Class Members – prefix for private fields, methods, and static members
00:15:24 Classes — Subclassing with extends – inheritance, super() in constructor, super.method() calls
00:16:47 Operator instanceof – checking class membership including inheritance
