The document discusses React, Redux, and ES6/7 features. It begins with an overview of React lifecycles and class components. It then provides a brief introduction to Redux, including core concepts like actions, reducers, and unidirectional data flow. The document also includes an example to demonstrate how React and Redux can work together, with Redux managing application state in the store and React components interacting via container components.
«От экспериментов с инфраструктурой до внедрения в продакшен»FDConf
В процессе разработки инструментов для инфраструктурных нужд получилось изучить технологии, которые легли в основу нового стека фронтенд разработки для мобильной версии «Одноклассников».
В результате удалось решить следующие задачи:
— улучшение качества продукта за счёт юнит тестирования и методологии TDD;
— снижение порога входа для новых фронтенд разработчиков;
— автоматизация процессов разработки, сборки и тестирования.
В докладе рассматривается использование следующих технологий: karma, jasmine, webpack, bower и gulp.
This is the support of a course to teach mainly Redux, and Redux with React for Java and C# programmers. It is the third part of the course to recycle programmers from desktop app programming to web app programming. This course covers from history of Redux, its origin, step by step what is a reducer, and later concepts like reducer splitting, action handling, async and many more.

Redux - негласный победитель Flux соревнований, одна из трендовых библиотек 2015 года. Слишком "сырой" для продакшена? Нет, мы так не думаем! Используя силу функционального подхода и модель Event Sourcing'a, Redux позволяет гибко управлять состоянием вашего приложения. В докладе мы расскажем про то, как мы, используя связку Redux+React, переписали с нуля front-end одного из наших продуктов (Лидсканер | leadscanner.ru). Рассмотрим реальные плюсы и минусы данного стека, в частности: работу с side-effects, повторное использование компонентов, тестируемость.

Migrating from Flux to Redux. Why and how.Astrails
When I started to work with React back in Apr-2015 there were many libraries to manage the application flow. I decided to start with classical FB's Flux implementation to understand what's missed there. Eventually react-redux and redux solved most of issues I had with Flux. This talk is about practical aspects of migration from Flux to Redux.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

39. VAR VS LET/CONST
* var의문제점
http://chanlee.github.io/2013/12/10/javascript-variable-scope-and-hoisting
var
함수범위변수를선언및초기화
const
읽기전용상수를선언
let
블록범위지역변수를선언및초기화
40. VAR VS LET/CONST
var office = 'coupang';
var office = 'forward ventures'; // do not error occurred
console.log(office); // forward ventures
let color = 'blue';
let color = 'black'; // TypeError
let count = 0;
count = 1;
console.log(count); // 1
const apple = 'apple';
apple = 'samsung'; // error
const comic = { name: 'DragonBall', author: ‘Akira Toriyama' };
comic = { name: ‘One Piece', author: ‘Oda Eiichiro‘ }; // error
comic.name = ‘One Piece';
comic.author = ‘Oda Eiichiro';
console.log(comic); // name: One Piece, author: Oda Eiichiro
es6에서는 var 대신 let을 사용하고, 가급적이면 const를 사용하는 것을 추천
배열이나 객체의 변경도 막겠다면 immutablejs 등을 사용하는 것도 고려
41. ARROW FUNCTION
// function
[ 1, 3, 7 ].map(function(value) {
return value * 2;
});
// arrow function
[ 1, 3, 7 ].map(value => value * 2);
// object를 반환하는 arrow function
const toMap = name => {
return { name: name };
};
// object를 반환하는 arrow function 간략 표기
const toMap = name => ({ name: name });
// compare ‘this’ with arrow function and function
const object = {
f1: function() {
console.log('f1', this);
function f1_1() { console.log('f1_1', this) }
setTimeout(f1_1, 1000);
setTimeout(() => { console.log('f1_2', this) }, 1000);
},
f2: () => {
console.log('f2', this);
function f2_1() { console.log('f2_1', this) }
setTimeout(f2_1, 1000);
setTimeout(() => { console.log('f2_2', this) }, 1000);
}
};
object.f1(); // Object, Window, Window
object.f2(); // Window, Window, Window
arrowfunction에서의this는arrowfunction이정의된지점의this값과같다
42. DEFAULT PARAMETERS
// 파라미터 기본값이 없는 경우
function increase(number) {
if (typeof number === 'undefined') return '[ERROR] number is undefined’;
return number + 1;
}
console.log(increase()); // [ERROR] number is undefined
console.log(increase(undefined)); // [ERROR] number is undefined
console.log(increase(10)); // 11
// 파라미터 기본값을 할당한 경우
function increase(number = 0) {
return number + 1;
}
console.log(increase()); // 1
console.log(increase(undefined)); // 1
console.log(increase(10)); // 11
OBJECT LITERAL : SHORTHAND
// es5
var x = 1;
var y = 2;
var object = {
x: x, y: y
};
// es6
const x = 1;
const x = 2;
const object = { x, y };
49. 알아두면 좋을 ES6 문법
Promise
Set / Map
yield / generator
비동기관련하여자주쓰이므로흐름정도는알아두면좋음
new Set([1,2,3]).has(2), new Map({foo:’bar’}).has(‘foo’)
