What is JavaScript?

JavaScript is a versatile programming language that allows developers to create dynamic and interactive features on web pages, such as animations, form validations, and real-time updates. It works alongside HTML and CSS to provide a complete user experience.

JavaScript is a core technology of the web and is widely used for both front-end and back-end development. It’s supported by all modern browsers and is essential for creating interactive and responsive websites and applications.

JavaScript Syntax

      
// program to solve quadratic equation
let root1, root2;

// take input from the user
let a = prompt("Enter the first number: ");
let b = prompt("Enter the second number: ");
let c = prompt("Enter the third number: ");

// calculate discriminant
let discriminant = b * b - 4 * a * c;

// condition for real and different roots
if (discriminant > 0) {
    root1 = (-b + Math.sqrt(discriminant)) / (2 * a);
    root2 = (-b - Math.sqrt(discriminant)) / (2 * a);

    // result
    console.log(`The roots of quadratic equation are ${root1} and ${root2}`);
}

// condition for real and equal roots
else if (discriminant == 0) {
    root1 = root2 = -b / (2 * a);

    // result
    console.log(`The roots of quadratic equation are ${root1} and ${root2}`);
}

// if roots are not real
else {
    let realPart = (-b / (2 * a)).toFixed(2);
    let imagPart = (Math.sqrt(-discriminant) / (2 * a)).toFixed(2);

    // result
    console.log(
    `The roots of quadratic equation are ${realPart} + ${imagPart}i and ${realPart} - ${imagPart}i`
  );
