React is a JavaScript library created by Facebook that allows building of user interfaces through components. Components are independent and reusable bits of code that return HTML via a render function. There are two types of components: class components that require a render method and extend React.Component, and function components that behave similarly but are simpler plain JavaScript functions. Props and state are used to pass data between components - props are immutable while state allows re-rendering on change.

One-way data flow for predictable state management.
Rich ecosystem with a large number of libraries and community support.
3.What is JSX?
JSX (JavaScript XML) is a syntax extension used by ReactJS to describe the structure and appearance of UI components. It allows developers to write HTML-like code in JavaScript.
4. What is a component in ReactJS?
A component in ReactJS is a reusable and independent piece of UI that encapsulates the logic and presentation of a specific part of the user interface. Components can be composed together to build complex UIs.
5. What is the difference between functional and class components in ReactJS?
Functional components are simple JavaScript functions that accept props as input and return JSX as output. They are easier to read, test, and optimize. Class components are JavaScript classes that extend the React.Component class. They have additional features like lifecycle methods and local state.
6. What are hooks in ReactJS?
Hooks are functions introduced in React 16.8 that allow developers to use state and other React features in functional components. They provide a way to reuse stateful logic between components.
7. Explain the concept of state in ReactJS.
State is an object that holds data specific to a component. It represents the mutable part of the component’s data and can be updated using the setState() method. When state changes, React re-renders the component to reflect the new state.
8. What is the significance of keys in ReactJS lists?
Keys are used in ReactJS lists to help identify each item in the list uniquely. They improve performance and help React efficiently update and reorder the list when needed.
9. What is the purpose of the useEffect hook?
The useEffect hook is used to perform side effects in functional components. It allows you to manage lifecycle events, such as fetching data, subscribing to events, or manually manipulating the DOM.
10. What is the difference between controlled and uncontrolled components?
Controlled components are those in which the component’s state is controlled by React. The component receives its current value via props and notifies changes using callback functions. Uncontrolled components, on the other hand, manage their own state internally using refs and are controlled by the DOM.

React js is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It allows creating reusable UI components that can be nested to build complex applications. A React component may maintain internal state and re-render when data changes. React uses a declarative paradigm that makes code more predictable and easier to debug.
To use React, install Node packages and create a new project using create-react-app. Components let you break up the UI into reusable pieces responsible for rendering HTML. Components can be stateful class components or stateless function components. Components can be created using ES6 class syntax or function syntax and can be nested. Choosing between class and function depends on requirements like using

This document describes an automated approach called ReactCodemod for refactoring class-based React components to function components using hooks. It proposes using the jscodeshift API to parse code into an abstract syntax tree (AST), identify code that needs refactoring, transform the AST by manipulating nodes, and regenerate the output code. The key steps are to import required hooks, replace state with useState, add const before class properties, remove references to 'this', replace setState with a setter function, and replace lifecycle methods with corresponding hooks. ReactCodemod aims to save developer time and effort compared to manual refactoring. It provides an architecture including a transform module that runs the refactoring logic on the AST,

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
