FAQ

The main categories of JavaScript patterns include object-creational patterns, structural patterns, behavioral patterns, and architectural patterns.

Mastering JavaScript patterns helps developers write code more clearly and efficiently, improve code architecture, catch up with team members, and potentially become a consultant or mentor with better skills and deeper understanding of software principles.

The factory pattern is about defining a method for creating objects in a superclass, but allowing subclasses to alter the type of objects that will be created. It helps in creating a function that produces additional objects while maintaining specific principles.

The singleton pattern ensures that a class has only one instance and provides a global point of access to it. This pattern is useful for scenarios requiring a single shared resource or centralized management, such as logging utilities or database connections.

The observer pattern involves a subject (or publisher) that maintains a list of its dependents (observers or subscribers) and notifies them of any state changes. This pattern is useful for implementing distributed event handling systems, such as in user interface frameworks.

Learning JavaScript patterns sets a normal developer apart from a skilled developer. It improves coding principles and problem-solving abilities, helps make better decisions about code architecture and design, and leads to fewer bugs, greater job satisfaction, and less stress about production issues.

Yes, examples include the factory pattern in Next.js for creating dictionary services, the adapter pattern in Next.js server features, the decorator pattern in Node.js for handling data events, and the MVC pattern in Angular for structuring applications.

The decorator pattern allows you to wrap an existing object or function with new behavior without altering its structure. It's like adding a layer of wrapping paper around a gift, enhancing or modifying its functionality dynamically.

The adapter pattern acts as a bridge between two incompatible interfaces, allowing them to work together. It converts the interface of a class into another interface that a client expects, facilitating compatibility between different systems or components.

The composite pattern lets you build a tree structure of objects where individual objects and groups of objects (composite objects) are treated the same way. It's useful for hierarchical data structures like organizational hierarchies or file systems.

Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up).
Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too.
Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step.
(Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components a better understanding of how each React hook can be used.You will learn all about the pros and cons of the various hooks. You will learn when to use useState() versus useReducer(). We will look at using useContext() efficiently. You will see when to use useLayoutEffect() and when useEffect() is better.

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn

Routing in React 18 and Beyond
Top Content
Routing in React 18 brings a native app-like user experience and allows applications to transition between different environments. React Router and Next.js have different approaches to routing, with React Router using component-based routing and Next.js using file system-based routing. React server components provide the primitives to address the disadvantages of multipage applications while maintaining the same user experience. Improving navigation and routing in React involves including loading UI, pre-rendering parts of the screen, and using server components for more performant experiences. Next.js and Remix are moving towards a converging solution by combining component-based routing with file system routing.

React 18's concurrent rendering, specifically the useTransition hook, optimizes app performance by allowing non-urgent updates to be processed without freezing the UI. However, there are drawbacks such as longer processing time for non-urgent updates and increased CPU usage. The useTransition hook works similarly to throttling or bouncing, making it useful for addressing performance issues caused by multiple small components. Libraries like React Query may require the use of alternative APIs to handle urgent and non-urgent updates effectively.
