React

Certainly, Reactjs is a JavaScript library developed by Facenook for building user interfaces. It allows developers to create reusable UI components and effciently manage the state of their applications. Here are some key aspects of Reactjs.


Component-Based Architecture: ReactJS follows a component-based architecture, where the user interface is divided into small, reusable components. Components encapsulate their own logic, state, and rendering, making it easier to build and maintain complex user interfaces.



Virtual DOM: ReactJS uses a virtual representation of the DOM (Document Object Model), known as the Virtual DOM. When the state of a component changes, React updates the Virtual DOM.



JSX: JSX is a syntax extension for JavaScript used in React. It allows developers to write HTML-like code within JavaScript, making it easier to describe the structure and appearance of components. JSX code is transpiled to regular JavaScript using tools like Babel before being executed in the browser.


Hooks: React introduced Hooks in version 16.8 as a way to use state and other React features in functional components. Hooks allow developers to write reusable logic and manage state within functional components without the need for class components. The most commonly used hooks are useState for managing state and useEffect for handling side effects such as fetching data or subscribing to events.


React Router: React Router is a popular routing library for React applications. It enables developers to create single-page applications with multiple views and handles routing between different components based on the URL.


State Management: React provides a flexible ecosystem of state management solutions. While React's built-in state management (useState ) is suitable for managing local component state, more complex applications may benefit from additional state management libraries like Redux. These libraries help manage global application state and provide predictable ways to update and access the state.


ReactJS has gained widespread popularity due to its performance, reusability, and declarative approach to building user interfaces. It has large community.

 Reducer.jsx

 

 

 case REMOVE_TO_CART:
           
            console.log("REMOVE_FROM_CART condition", action)
            const remainingItem = data.filter((item) => item.id !== action.data);
            console.log("RemainingItem", remainingItem)
            return [ ...remainingItem ];

 

 

 

 Simple open Reducer.jsx and put a new case REMOVE_TO_CART and apply filter function with condition.

 

Full Code

 

import { ADD_TO_CART, EMPTY_CART, REMOVE_TO_CART } from './Constant';
export const cartData = (data = [], action) => {
    switch(action.type)
    {
        case ADD_TO_CART:
            console.log("ADD_TO_CART CONDITION", action)
            return [action.data,  ...data];
        case REMOVE_TO_CART:
            console.log("REMOVE_FROM_CART condition", action)
            const remainingItem = data.filter((item) => item.id !== action.data);
            console.log("RemainingItem", remainingItem)
            return [ ...remainingItem ];
        case EMPTY_CART:
            console.log("EMPTY_CART condition", action)
            data = []
            return [ ...data ]
        default:
            return data;
    }
