Uncontrolled form input in React-JS

Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component { constructor ( props ) { super ( props ); this . fun = this . fun . bind ( this ); //event method binding this . input = React . createRef ();...

JSP Page design using Internal CSS

DSA in C# | Data Structure and Algorithm using C#

DSA in C# | Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25; // 'age' stores an integer value. bool isStudent = true; // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...
