Mastering React: A Comprehensive Guide to Building Dynamic User Interfaces

useEffect is a Hook in React that allows you to manage side effects in your functional components. A side effect is any state or behavior change that occurs outside of the render function . Some common examples of side effects include: Fetching data from an API Setting and updating a timer Listening to and responding to browser events Updating the document title With useEffect , you can run these side effects and keep your components clean and focused on rendering UI. Usage syntax : useEffect takes two arguments :  The first argument to useEffect is a function that contains your effect code. This function is called every time your component is rendered, and its purpose is to manage your side effect. The second argument is an optional argument to useEffect is an array of dependencies . This array is used to tell React when to re-run your effect. There can be three scenarios :  I. Passing a dependency array with some states: In this case, useEffect will r...

useState is a hook in React that allows you to add a state to your functional components. A state is an object that holds data that can change over time, such as user input or dynamic values, and it is used to render dynamic and interactive content in your component. Before the introduction of hooks in React, state management was limited to class components. With useState , you can manage state in functional components, making it easier to manage and maintain your code. Usage syntax :  Note: It’s a widely accepted and followed practice to destructure the returned array into named variables, such as something and setSomething , for better readability and ease of understanding. This is not a requirement, but a recommended best practice in the community. Now let’s talk about its parameter and return value: Parameter : initialState : The initial value of the state. It can be a value of any type, but if you provide functions, it stores the value return value of that functio...

React Hooks is a feature introduced in React 16.8 that changed the way React components are written.  What are Hooks? React Hooks are simply JavaScript functions that allow you to reuse stateful logic and other React features without writing a class component. They provide a way to use state and other React features in functional components, making it easier to share and reuse logic across components. Why were Hooks introduced? Hooks were introduced to solve some of the problems that developers faced while using class components in React. Class components can become complex and difficult to understand as the state and logic grow, leading to difficulties in sharing and reusing code. Hooks provide a way to solve these problems by allowing developers to write simple and reusable logic that can be shared across components. Benefits of using Hooks: a. Reusable logic: Hooks allow you to share and reuse stateful logic across components, making your code more maintainable and reusable. b. ...
