React forwardRef explained: Usage, alternatives, and React 19 update
- forwardRef is a React utility that lets a parent component pass a ref through a child component to access the child’s DOM node or instance directly.
- It enables direct interaction between parent and child components, especially when dealing with higher-order components or wrapper components.
- Refs in React allow access and interaction with DOM elements directly, bypassing typical data flow and enabling actions beyond props and state.
- Common use cases for refs include managing focus, text selection, media playback, triggering animations, integration with third-party DOM libraries, and measuring element dimensions.
- While powerful, refs should be used sparingly to maintain code clarity and readability, favoring props and state for data flow.
- Creating and attaching refs in class components involves using createRef to create a ref and associating it with a DOM element for direct manipulation.
- In functional components, refs cannot be attached directly, but forwardRef allows for ref forwarding, enabling parent components to interact with child components' DOM elements.
- useImperativeHandle works with forwardRef to customize instance values exposed when using refs, providing more control and functionality.
- Refs should not be used unnecessarily in React, especially for unnecessary DOM manipulation, accessing internal states of child components, or replacing controlled components.
- Choose between forwardRef, useRef, callback refs, React Context, and useImperativeHandle based on the component hierarchy and the need for direct DOM access.

How to use the useEffect hook in React: A complete guide
- useEffect enables handling side effects directly inside functional components in React, from data fetching to DOM manipulation.
- This guide aims to clarify the core concepts behind useEffect, covering real-world lessons and effective usage patterns.
- Basic usage of useEffect involves running code once when the component mounts: useEffect(() => { // Code to run once }, []);
- useEffect in React is for handling effects like fetching data or DOM manipulation and differs significantly from class-based lifecycle methods.
- Understanding basic JavaScript concepts is crucial when using useEffect to avoid problems with outdated props or state values.
- Key points include defining effects clearly, controlling dependencies, adding cleanup logic, avoiding unnecessary effects, and keeping effects efficient.
- useEffect is commonly used for asynchronous tasks like data fetching, allowing components to manage actions after mounting.
- Effects run after rendering and update in React, providing asynchronous behavior without blocking the UI.
- Advice for seasoned React developers includes transitioning from class-based components to functional components with Hooks.
- The control flow of effects in React includes initial render/mounting, subsequent renders, cleanup function execution, and unmounting.

React to Surprises: Stable-by-Design Neural Feedback Control and the Youla-REN
- Researchers propose a structure for stabilizing nonlinear policies for learning-based control using a combination of Youla-Kucera parameterization and robust neural networks like recurrent equilibrium network (REN).
- The parameterizations introduced are unconstrained, enabling optimization with first-order methods while ensuring closed-loop stability.
- The study examines nonlinear dynamics, partial observation, and incremental closed-loop stability requirements, finding that a contracting and Lipschitz Youla parameter leads to closed loops with similar properties.
- Numerical experiments demonstrate the effectiveness of the proposed parameterization in learning controllers with stability guarantees for scenarios like economic rewards, short training horizons, and uncertain systems.
