OOP, What is it?
Something about objects and classes
Encapsulation
Polymorphism
Abstraction
Inheritance

Слайд 3

Why do we need it?
Computer doesn’t care how elegant your code

is, people do.

Creating of models works better if you have right amount of right abstractions.

Any statement which may have only one meaning within its context can be used as a piece of program code.

Слайд 4

More about programming paradigms
Imperative
Functional
Logic programming
Declarative

Слайд 5

Web application in general
Runs in browser
Requires client-server communication
Interactivity
No complex computing

Слайд 6

Let’s talk about JavaScript
No Classes
Everything but primitives is an object

Слайд 7

JS Data Types

Слайд 8

Aliases

Слайд 9

First-class function

Слайд 10

How to get a class

Слайд 11

What about other OOP concepts?
Encapsulation

Слайд 12

Scope

Слайд 13

More about closure
(A Counter Dilemma)

Слайд 14

Inheritance
prototype
Anything wrong with this?
“Mammal” is not a “class”

Слайд 15

Use prototype properly

Слайд 16

What is “this”?

Слайд 17

"apply" and "call" methods

Слайд 18

Software design pattern
They're not supposed to make your life more difficult

They're not a panacea

Слайд 19

Types of patterns

Слайд 20

Singleton

Слайд 21

Module

Слайд 22

Mediator

Слайд 23

Conclusions
Everything including functions is variable
Everything but primitives is object
Primitive variables are

variables object variables are aliases

Function called with new turns out to class constructor

prototype can be used for defining class methods and properties

Use closure for encapsulation

Don’t forget about context
