React's context API has always been labelled as experimental, but from the advent of Redux it has been used in all the most exciting react libraries. It's now a stabilised feature so now is the perfect time to learn the new context API and how render props can simplify your code.
JS Fest 2019. Glenn Reyes. With great power comes great React hooks!JSFestUA
The React team has been working hard on changing the game of writing declarative components: Hooks! With React Hooks we are now able to use the capabilities of class components in functional components. In this talk we are going to discover the Hooks API and explore some exciting patterns using them.
1) Rxjs provides a paradigm for dealing with asynchronous operations in a synchronous way using observables. Observables allow representing push-based data streams and provide operators to compose and transform these streams.
2) Operators like map, filter, and switchMap allow manipulating observable streams and their values in various ways. Common patterns include cascading asynchronous calls, parallelizing multiple requests, and retrying or error handling of streams.
3) Schedulers allow bending time and virtual clocks, enabling testing asynchronous code by controlling when asynchronous operations complete. Marble testing uses descriptive patterns to visually test observable streams and operator behavior.

Very quick introduction to the language R. It talks about basic data structures, data manipulation steps, plots, control structures etc. Enough material to get you started in R.
This document discusses the evolution of component composition in React, from mixins to higher-order components. It describes how mixins were commonly used in early React but caused problems with name clashes and complexity. React then introduced classes but removed mixin support. Developers experimented with inheritance but it did not allow for pure composability. Later, higher-order components were introduced as a way to compose logic in a non-hierarchical manner by wrapping one component inside another. The document demonstrates how to build a controlled input component using higher-order components to separate concerns into model, view and controller logic in a modular, reusable way. It also discusses debugging techniques using the Recompact library which treats components as streams of props.

This document discusses React hooks and how they can be used to improve on class components. React hooks allow logic to be extracted from components and reused through custom hooks. Some key points:
- Hooks let you use state and other React features without writing a class. They don't work inside classes.
- Built-in hooks include useState, useEffect, useContext. Custom hooks let you extract component logic into reusable functions.
- Hooks solve problems with classes like making 'this' unnecessary and splitting logic from UI. They follow two rules: only call at the top level and separate dependencies from UI.
This document discusses React hooks and how they enhance functional components. It explains that hooks allow functional components to maintain state and lifecycle methods like class components. The key hooks discussed are useState for managing state, useEffect for side effects like data fetching, and useCallback and useMemo for optimization. Custom hooks are also covered as a way to extract reusable logic. Overall, hooks improve on class components by making code more modular, reusable and easier to test.

Pragmatic functional refactoring with java 8 (1)RichardWarburton
You may be hearing a lot of buzz around functional programming. For example, Java 8 recently introduced new features (lambda expressions and method references) and APIs (Streams, Optional and CompletableFutures) inspired from functional ideas such as first-class functions, composition and immutability.
However, what does this mean for my existing codebase?
In this talk we show how you can refactor your traditional object-oriented Java to using FP features and APIs from Java 8 in a beneficial manner.
We will discuss:
* How to adapt to requirement changes using first-class functions
* How you can enhance code reusability using currying
* How you can make your code more robust by favouring immutability over mutability
* How you can design better APIs and reduce unintended null pointer exceptions using an optional data type
This document provides an overview of React.js and key concepts like components, props, state, and JSX syntax. It also discusses performance techniques like virtual DOM and how React efficiently re-renders. Additionally, it covers related topics like Redux for state management and separating concerns with a component architecture.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

▸ Functions being first class values means we can use them as
parameters to enable more flexible code re-use
▸ Using functions as parameters allows highly customisable
shared components, complete with state and lifecycle hooks.
▸ React Context lets you share state across the tree of your
application
▸ Context still uses the React tree. This means it works with
server side rendering and you can safely use it in parts of your
app, as well as using it as a whole app solution.
