Create a slide summarizing the core React Hooks (useState, useEffect, useMemo, useCallback, useRef, and the Rule of Hooks), their primary use cases, and concise best practice tips for each. The slide should be visually appealing and easy to understand, with a professional design suitable for a presentation or educational material. Include speaker notes that elaborate on each hook, emphasizing best practices, potential pitfalls, and trade-offs to consider. The design should incorporate smooth animations for a dynamic presentation. The target audience is developers familiar with React, seeking to refine their understanding and usage of hooks.
1. Set the frame: this is a fast tour of the core hooks we reach for in daily React—what each is for, and the one-sentence guidance.
2. useState: Emphasize keeping state minimal. Encourage deriving values (like counts, filters, computed flags) instead of storing duplicates that drift out of sync.
3. useEffect: Explain it as the bridge to the outside world—subscriptions, timers, DOM, network. Stress small, focused effects with full dependency lists, and preferring event handlers or derived rendering when possible.
4. useMemo: Position it as a cache for expensive computations. Only introduce when you can feel or measure the cost, or when a stable value prevents churn downstream.
5. useCallback: Clarify it stabilizes function identity to satisfy dependency arrays and memoized children. On its own it does not make code faster—value comes from avoiding needless re-renders in children.
6. useRef: Use it as a mutable box for values that don’t trigger re-renders (timestamps, previous values) and for DOM node references. Great for imperative escapes and integrating third‑party widgets.
7. Close with the Rule of Hooks: call hooks at the top level, same order every render—never inside loops or conditionals. That’s how React preserves state correctly.
8. Invite questions on trade-offs or real cases where these rules simplify a component.

Frequently Asked Questions
What is the purpose of React Hooks?
React Hooks allow functional components to use state and other React features without writing a class. They provide a simpler, more concise way to manage state, side effects, and other aspects of component logic, leading to more readable and maintainable code. Keywords: React, Hooks, functional components, state management, side effects, JavaScript.
Why is it important to keep state minimal in React?
Minimizing state reduces complexity and improves performance. Deriving values instead of storing redundant data prevents inconsistencies and simplifies updates, making components easier to reason about and debug. Keywords: React, state management, performance optimization, data consistency.
When should I use useMemo and useCallback?
Use `useMemo` to cache expensive calculations and prevent redundant computations. Use `useCallback` to prevent unnecessary re-renders of child components when passing functions as props, ensuring referential equality. Overuse can negatively impact performance, so apply them strategically. Keywords: React, useMemo, useCallback, performance optimization, memoization, referential equality.
Create a slide contrasting React anti-patterns with recommended practices. It should highlight common mistakes like prop drilling, storing derived state, overusing useEffect, and stale closures. Then, present the better alternatives: lifting state, deriving values on render, using TanStack Query/SWR, and stabilizing handlers. Include brief migration notes for transitioning from older patterns and links to relevant resources like the 'You Might Not Need an Effect' article and the 'Bulletproof React' repository. The slide should have a professional, clean design and clear explanations.
Create a slide visualizing the UX onboarding flow for a software product, highlighting the key steps a user takes from initial signup to achieving their first value within the application. The slide should emphasize the critical actions and criteria for success at each step. Include micro-interactions or UI thumbnails to illustrate each stage. Additionally, mention edge cases and alternative paths within the onboarding process, such as SSO logins or invitation-based onboarding. Provide speaker notes elaborating on each step and addressing the edge cases.
Create a slide visualizing the information architecture of a web application. The visualization should depict a hierarchical structure with the main app at the top, branching into four primary sections (Dashboard, Projects, Billing, Settings). Each section further expands into 1-2 core tasks (e.g., Dashboard -> Quick Stats, Reports). The visual style should be clean and minimal, using boxes for elements and lines to represent connections. Include tooltips on hover to provide brief descriptions of each element. The overall message should emphasize how clear information architecture improves navigation and reduces cognitive load for users.
Explain React Server Components (RSCs), their purpose, and advantages. Include a visual representation of the server-client interaction, highlighting the server rendering, client hydration, and the impact on bundle size. Explain how RSCs improve performance by rendering components on the server and reducing the amount of JavaScript sent to the client. Emphasize the benefits like zero client JS for server-only parts, data proximity to the database, smaller bundles, faster Time To Interactive (TTI), and interactivity enabled by client component boundaries. Also, explain the concept of hydration and how it works with RSCs.
This slide is the opening slide for a case study presentation about the development of a SaaS product called Dlidebook. The presenter wants to convey a sense of calm, modern professionalism, and highlight their role in the project. The slide includes a title, subtitle, project details (product name, role, year), and a subtle animated accent. The background features a soft gradient and a moving dot grid to add visual interest. The animation sequence is designed to draw the audience's attention to the key elements of the slide in a structured manner, starting with the title and then revealing the subtitle and project details. The speaker notes provide further context about the presentation's flow and the design choices made for the slide.
Create a slide about common pitfalls when using the useEffect hook in React, and present the better pattern for using it effectively. The slide should visually highlight the common mistakes (missing dependencies, heavy synchronous work, fetching data) and contrast them with the correct approach (deriving from props/state, data fetching in data layer, using effects for subscriptions and cleanup). Include a code example demonstrating the correct usage of useEffect with proper dependency array and cleanup function. The target audience is React developers. The slide should be engaging and easy to understand.
