Mastering React Series: Hooks





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. Simple code: Hooks make it easier to understand and write code, reducing the complexity of class components and making it easier to follow the logic.

c. Improved performance: Hooks allow you to optimize the performance of your components, as they give you greater control over when the component should re-render.

d. Easy testing: Hooks make it easier to test your components, as they allow you to isolate the stateful logic and test it in isolation.

List of all the built-in hooks in React

Note: We can also create our own custom hooks. We will dive deep into these hooks in later blogs.

Conclusion:

React Hooks is a powerful feature that has changed the way React components are written. They provide a simple and effective way to share and reuse stateful logic and other React features, making it easier to write and maintain your React code. Whether you're new to React or an experienced developer, Hooks are a great tool to have in your arsenal and are definitely worth exploring further.

Mastering React Series: The Virtual DOM & Reconciliation

Image
Before we dive into the Virtual DOM, let's first understand what a DOM is. The Document Object Model (DOM) is a tree-like structure that represents the HTML of a web page and enables JavaScript to manipulate its content and structure. The DOM is a live representation of the web page and changes to the DOM are immediately reflected in the web page. The Virtual DOM, on the other hand, is a lightweight in-memory representation of the actual DOM. When the state of a React component changes, React updates the Virtual DOM, instead of the actual DOM, to determine the most efficient way to update the UI. This process is known as reconciliation. Reconciliation is done by the diffing algorithm, which is a breadth-first approach process that compares the current and previous versions of a React component's Virtual DOM to determine the most efficient way to update the actual DOM. The goal of the diffing algorithm is to minimize the number of changes made to the actual DOM, resulting in a f...

Mastering React Series: Class Components Life Cycle Methods

Image
Class components in React have several lifecycle methods that are called at different stages of a component's lifecycle. These methods provide a way to perform actions at specific points in a component's lifecycle, such as when the component is mounted, updated, or unmounted. Understanding the class component lifecycle methods and their usage is critical for building performant and efficient React applications. Different life cycle methods are :  constructor componentWillMount render componentDidMount componentWillReceiveProps shouldComponentUpdate componentWillUpdate componentDidUpdate componentWillUnmount Here is a detailed explanation of the class component lifecycle methods:   I. Constructor :   The constructor method is a special method in class components that is called when a component is created and initialized. It is used to set the initial state of a component and bind event handlers to the component instance. The constructor method is the first method that is...

Mastering React Series: React Components

Image
React Components are the building blocks of any React application. They are independent, reusable, and composable units that define a piece of the UI. In React, everything is a component, including the UI, forms, modals, etc. Types of React Components There are two main types of React Components: Class Components Function Components Class Components Class components are JavaScript classes that extend React.Component class. They use a class-based syntax to define a component, and they are used when you need to handle state or lifecycle methods. Example:   Lifecycle Methods in Class Components Class Components have lifecycle methods that allow you to perform actions at specific points during the component's lifecycle. These methods are called automatically by React, and they give you control over the component's behavior and state. Examples of lifecycle methods include: componentDidMount: called after the component has mounted (added to the DOM) componentDidUpdate: called after t...
