Let’s talk javascript : Part 2 (Objects and prototypes)
- Objects in JavaScript are collections of properties and can be created using object literal, constructor, Object.create(), and class keyword.
- Object properties have a property descriptor that defines its attributes such as writable, enumerable and configurable.
- Getter and Setter allow us to define custom behavior for accessing and setting property values.
- A prototype is an object that exists in every function in JavaScript, and objects have a __proto__ property assigned to them.
- Inheritance works in JavaScript by having the object __proto__ link to the prototype of the constructor function that created it.
- We can add properties to a function's prototype, which will then be inherited by objects created using that function as a constructor.
- prototype shadowing occurs when an object looks for a property in its own properties first and then in its prototype.
- We can change the prototype object of a function to point to an entirely new object.
- Object.create() sets up a prototype chain without invoking a constructor function, while using new would call the constructor function.
- Next, the article covers design patterns in JavaScript in an intermediate-level topic.
