What is JavaScript ?

JavaScript is one of the web’s most powerful and adaptable programming languages. It powers most websites’ dynamic behaviour. JavaScript is a lightweight object-oriented programming language that is used to script web pages by several websites. When applied to an HTML document, it is an interpreted, full-featured programming language that enables dynamic interactivity on websites. It was first released in 1995 to allow users to add programs to web pages in the Netscape Navigator browser, JavaScript projects for 11th and 12th classes

1. JavaScript Calculator

JavaScript Calculator

Calculators are fun, so, to begin with, we will build a simple Calculator using JavaScript. We’ll utilize fundamental JavaScript functions to make all the components work, as well as simple HTML and CSS. We’ll use HTML to display buttons and numbers, and CSS to make them more appealing. Furthermore, we’ll utilize JavaScript to make the buttons do their jobs.

Here’s the Source Code.

4. Number Guessing

Number Guessing

This is a simple command-line game where the computer generates a random number between 1 and 100, and the user has to guess it. The game provides feedback to the user on whether their guess is too high or too low.

Here’s the Source Code.

5. Weather Apk JavaScript

Weather Apk

The Weather App is a lightweight and user-friendly application built using JavaScript, HTML, and CSS. It provides users with real-time weather information for their location, helping them plan their day accordingly.

6. Aspect Ratio Calculator

In this project, we will create a simple web application using JavaScript to calculate and adjust the aspect ratio of images. Aspect ratio is the proportional relationship between the width and height of an image. Maintaining the correct aspect ratio is crucial for preserving the quality and visual integrity of images, especially when resizing or displaying them on different devices.

7. Tic Tac Toe Game

In this project, we’ll be creating a classic game of Tic Tac Toe using HTML, CSS, and JavaScript. Tic Tac Toe is a simple two-player game where each player takes turns marking spaces in a 3×3 grid. The objective is to get three of your marks (either “X” or “O”) in a row, column, or diagonal.

Key features of our Tic Tac Toe game will include:

1. A 3×3 grid where players can mark their moves.
2. Alternating turns between two players (one playing “X” and the other playing “O”).
3. Detection of winning combinations and declaring a winner.
4. Handling of ties when the grid is filled without a winner.
