Today I have learned javascript lable and dropdown

 A labeled statement is any statement that is prefixed with an identifier. You can jump to this label using a break or continue statement nested within the labeled statement.

A JavaScript statement. break can be used within any labeled statement, and continue can be used within labeled looping statements.

You can use a label to identify a statement, and later refer to it using a break or continue statement. Note that JavaScript has no goto statement; you can only use labels with break or continue.

Any break or continue that references label must be contained within the statement that's labeled by label. Think about label as a variable that's only available in the scope of statement.

We have styled the dropdown button with a background-color, padding, hover effect, etc.

The .dropdown class uses position:relative, which is needed when we want the dropdown content to be placed right below the dropdown button (using position:absolute).

The .dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). Note the min-width is set to 160px. Feel free to change this. Tip: If you want the width of the dropdown content to be as wide as the dropdown button, set the width to 100% (and overflow:auto to enable scroll on small screens).

Instead of using a border, we have used the box-shadow property to make the dropdown menu look like a "card". We also use z-index to place the dropdown in front of other elements.


 <label><input type="radio"  /> male</label>
        <label><input type="radio"   /> female</label>
        <label><input type="radio"  /> others</label>
        <label><input type="checkbox"  /> name</label>
        <label><input type="checkbox"  /> mobilenumber</label>
        <br></br>
        <br></br>
        <label>Choose a subject:</label>
        <select name="subject" id="subject">
  <option>tamil</option>
  <option >english</option>

Building a Full-Stack Student Management System with React.js and NestJS

  🚀 My Journey Creating a Student Management System 🌟 I'm excited to share my recent project — a Student Management System ! This project gave me hands-on experience in building a full-stack application, enhancing both my frontend and backend development skills. 💡 Project Overview The Student Management System is designed to help educational institutions efficiently manage student data, including enrollment, attendance, and performance. The goal was to create a user-friendly platform for both students and administrators. 🔨 Tech Stack Used ✅ Frontend: JavaScript, HTML, CSS, React.js ✅ Backend: TypeScript, NestJS, Node.js ✅ Database: MongoDB (with _id for unique identifiers) 🌟 Key Features ✔️ Student Registration – Easy registration with unique ID management ✔️ Attendance Tracking – Real-time updates on student attendance ✔️ Performance Reports – Generate and view student performance reports ✔️ Admin Panel – Secure access for administrators to manage student...

Today I have solved the problem in javascript

 Consider the following scenario: there are N mice and N holes placed at integer points along a line. Given this, find a method that maps mice to holes such that the largest number of steps any mouse takes is minimized.Each move consists of moving one mouse one unit to the left or right, and only one mouse can fit inside each hole.For example, suppose the mice are positioned at [1, 4, 9, 15], and the holes are located at [10, -5, 0, 16]. In this case, the best pairing would require us to send the mouse at 1 to the hole at -5, so our function should return 6. const mice = [1, 4, 9, 15]; const holes = [10, -5, 0, 16]; function minSteps(mice, holes) {    mice.sort((a, b) => a - b);     holes.sort((a, b) => a - b); let maxSteps = 0;     for (let i = 0; i < mice.length; i++) {         let steps = Math.abs(mice[i] - holes[i]);         if (steps > maxSteps) {             maxStep...

Today I have solved problem in javascript

 You are given an array X of floating-point numbers x1, x2, ... xn. These can be rounded up or down to create a corresponding array Y of integers y1, y2, ... yn. Write an algorithm that finds an appropriate Y array with the following properties: The rounded sums of both arrays should be equal. The absolute pairwise difference between elements is minimized. In other words, |x1- y1| + |x2- y2| + ... + |xn- yn| should be as small as possible. For example, suppose your input is [1.3, 2.3, 4.4]. In this case you cannot do better than [1, 2, 5], which has an absolute difference of |1.3 - 1| + |2.3 - 2| + |4.4 - 5| = 1. const inputArray = [1.3, 2.3, 4.4]; const resultArray = roundArray(inputArray); function roundArray(inputArray) {     const n = inputArray.length;     const roundedArray = [];     let roundedSum = 0; for (let i = 0; i < n; i++) {         consat roundedValue = Math.round(inputArray[i]);         rounded...
